Is using config to change image of button in function wrong?

I was making python gui with tkinter
I wanted to change button's image if I push button
But it doesn't work.(I use config)
with some effort I found it work in main code
but still it doesn't work in fucntion that is connected to button
Here are the codes
from tkinter import *
from PIL import Image, ImageTk
# using by function
def select_precision():
overheal = image_resize((20, 20), "gui_project/item_simulation/overheal.png")
runepage_00.config(image=overheal)
def image_resize(size, link):
image = Image.open(link)
image = image.resize(size, Image.ANTIALIAS)
image = ImageTk.PhotoImage(image)
return image
root = Tk()
root.title()
precision = PhotoImage(file="gui_project/item_simulation/precision.png")
rune00 = PhotoImage(file="gui_project/item_simulation/domination.png")
runepage_precision = Button(root, width=20, height=20,\
image=precision, command=select_precision)
runepage_00 = Button(root, width=20, height=20, image=rune00)
runepage_precision.pack()
runepage_00.pack()
root.mainloop()
but if I change like this, the config works but I don't know why
from tkinter import *
from PIL import Image, ImageTk
def image_resize(size, link):
image = Image.open(link)
image = image.resize(size, Image.ANTIALIAS)
image = ImageTk.PhotoImage(image)
return image
root = Tk()
root.title()
precision = PhotoImage(file="gui_project/item_simulation/precision.png")
rune00 = PhotoImage(file="gui_project/item_simulation/domination.png")
runepage_precision = Button(root, width=20, height=20,\
image=precision, command=select_precision)
runepage_00 = Button(root, width=20, height=20, image=rune00)
# using inside the code
overheal = image_resize((20, 20), "gui_project/item_simulation/overheal.png")
runepage_00.config(image=overheal)
runepage_precision.pack()
runepage_00.pack()
root.mainloop()
to make it short
first was
def select_precision():
overheal = image_resize((20, 20), "gui_project/item_simulation/overheal.png")
runepage_00.config(image=overheal)
runepage_precision = Button(root, width=20, height=20,\
image=precision, command=select_precision)
runepage_00 = Button(root, width=20, height=20, image=rune00)
and second was
runepage_precision = Button(root, width=20, height=20,\
image=precision, command=select_precision)
runepage_00 = Button(root, width=20, height=20, image=rune00)
overheal = image_resize((20, 20), "gui_project/item_simulation/overheal.png")
runepage_00.config(image=overheal)

How to make a image viewer with left right functionality in tkinter?

I have bunch of links and labels in list to view those I want to make a image viewer with next, previous functionality. My links and labels for respective images are in list. Up to now I had tried this :
urls=[url,url1,url2,url3]
labels=["label 1","label 2","label 3","label 4"]
images=[]
for ur in urls:
raw_data = urllib.request.urlopen(ur).read()
im = Image.open(io.BytesIO(raw_data))
image = ImageTk.PhotoImage(im)
images.append(image)
Now I have images ready in images and now I want to display it in image viewer but only last image is visible in image viewer.
Label(root).grid(row=1,column=1)
for i in range(len(images)):
image_label=Label(root,image=images[i])
image_label.grid(row=1,column=2)
name=Label(root,text=labels[i])
name.grid(row=2,column=2)
def left():
image_label=Label(root,image=images[i-1])
image_label.grid(row=1,column=2)
def right():
image_label=Label(root,image=images[i+1])
image_label.grid(row=1,column=2)
left_button=Button(root,text="Left",command=left)
left_button.grid(row=2,column=1)
right_button=Button(root,text="Right",command=right)
right_button.grid(row=2,column=3)
Right button is not working and left button is working but for one time only. When I click left button second time then nothing is working.
Error while clicking in right button :
line 45, in right
image_label=Label(root,image=images[i+1])
IndexError: list index out of range

The code is pretty close to original posted example.
There is no lambda in Button, just straight forward command that gives access to left and right functions.
The name label is unnecessary as label objects already have a text attribute so I've integrated image and text into single label and increased the font size.
label compound is used to control where the image is display relative to the text, I've chosen top. That is, the image will be place above the text.
The use of global in functions keeps track of count
from tkinter import Tk, Label, Frame, Button
from PIL import ImageTk, Image
import io
import requests
import urllib
root = Tk()
urls = [url, url1, url2, url3]
labels = ["label 1","label 2","label 3","label 4"]
count = -1
images = []
for ur in urls:
raw_data = urllib.request.urlopen( ur ).read()
im = Image.open(io.BytesIO( raw_data ))
image = ImageTk.PhotoImage(im)
images.append(image)
def left( ):
global count
count = (count - 1) % len(images)
image_label.config(image = images[count], text = labels[count])
def right( ):
global count
count = (count + 1) % len(images)
image_label.config(image = images[count], text = labels[count])
image_label = Label(
root, image = images[count], font = "Helvetica 20 normal",
text = labels[count], compound = "top")
image_label.grid(row = 0, column = 0, columnspan = 2, sticky = "nsew")
Button(
root, text = "<< LEFT", command = left).grid( row = 1, column = 0, sticky = "ew")
Button(
root, text = "RIGHT >>", command = right).grid(row = 1, column = 1, sticky = "ew")
right( ) # display first image
root.mainloop()

Here's a way to do it by showing and hiding pairs of Labels with the image and it name on them. For development and testing purposes, it loads the images from disk instead of downloading them, but you can easily replace that with what you have in your question.
from pathlib import Path
from PIL import Image, ImageTk
from tkinter import Button, Tk, Label
root = Tk()
root.title('Image Viewer')
# Create thumbnails of all the images.
image_folder = '/path/to/image/folder'
images = []
for filepath in Path(image_folder).iterdir():
img = Image.open(filepath)
w, h = img.size
if w > h:
f = 100 / w
nw, nh = 100, int(f*h)
else:
f = 100 / h
nw, nh = int(f*w), 100
# Offsets to center thumbnail within (100, 100).
woff, hoff = (100-nw) // 2, (100-nh) // 2
img = img.resize((nw, nh), Image.BICUBIC) # Shrink so largest dimen is 100.
thumbnail = Image.new('RGBA', (100, 100), (255, 255, 255, 0)) # Blank.
thumbnail.paste(img, (woff, hoff)) # Offset keep it centered.
images.append(ImageTk.PhotoImage(thumbnail))
names = ['Name 1', 'Name 2', 'Name 3', 'Name 4']
def get_images():
"""Create all image and name Label pairs but initially hidden."""
global image_labels, name_labels
image_labels, name_labels = [], []
for i, (img, name) in enumerate(zip(images, names)):
image_label = Label(root, image=img)
image_label.grid(row=1, column=2)
image_labels.append(image_label)
name_label = Label(root, text=name)
name_label.grid(row=2, column=2)
name_labels.append(name_label)
hide(i)
def hide(i):
"""Hide specified image and name pair."""
image_labels[i].grid_remove()
name_labels[i].grid_remove()
def show(i):
"""Unhide specified image and name pair."""
image_labels[i].grid()
name_labels[i].grid()
def shift(direction):
"""Display the image and pair before or after the current one that is
`direction` steps away (usually +/-1).
"""
global current
hide(current)
current = (current + direction) % len(images)
show(current)
left_button = Button(root, text="Left", command=lambda: shift(-1))
left_button.grid(row=2, column=1)
right_button = Button(root, text="Right", command=lambda: shift(+1))
right_button.grid(row=2, column=3)
get_images()
current = 0 # Currently displayed image.
show(current)
root.mainloop()
Screenshot of it running:

Should just update a image label when shift left or right, not create a new label.
Using modulus % to find which one next turn.
To reduce code and executable, I use the image data in PySimpleGUI and simple name for image here.
import tkinter as tk
import PySimpleGUI as sg
def shift(num):
global index
index = (index + num) % size
label1.configure(image=images[index])
label2.configure(text =labels[index])
root = tk.Tk()
images = [tk.PhotoImage(data=image) for image in sg.EMOJI_BASE64_HAPPY_LIST]
size = len(images)
labels = [f'Image {i:0>2d}' for i in range(size)]
index = 0
label1 = tk.Label(root, image=images[index])
label1.grid(row=1, column=2)
label2 = tk.Label(root, text=labels[index])
label2.grid(row=2, column=2)
button1 = tk.Button(root, text="<LEFT", width=6, anchor='center', command=lambda num=-1:shift(num))
button1.grid(row=1, column=1)
button2 = tk.Button(root, text="RIGHT>", width=6, anchor='center', command=lambda num=+1:shift(num))
button2.grid(row=1, column=3)
root.mainloop()

You can try this :
from tkinter import Tk,Label,Button
from PIL import ImageTk,Image
import io
import requests
import urllib
root=Tk()
count=0 # To know the current image and label
urls=[url,url1,url2,url3]
labels=["label 1","label 2","label 3","label 4"]
images=[]
for ur in urls:
raw_data = urllib.request.urlopen(ur).read()
im = Image.open(io.BytesIO(raw_data))
image = ImageTk.PhotoImage(im)
images.append(image)
def change(direction): # Function to change image
global count
if direction=="left":
if count<=0:
count=len(urls)-1
else:
count-=1
else:
if count>=len(urls)-1:
count=0
else:
count+=1
name.config(text=labels[count])
image_label.config(image=images[count])
Label(root).grid(row=1,column=1)
image_label=Label(root,image=images[count])
image_label.grid(row=1,column=2)
left_button=Button(root,text="Left",command=lambda : change("left"))
left_button.grid(row=2,column=1)
name=Label(root,text=labels[count])
name.grid(row=2,column=2)
right_button=Button(root,text="Right",command=lambda : change("right"))
right_button.grid(row=2,column=3)
root.mainloop()

Image not appearing in Ttkinter window

What I'm trying to do is to display the image cover from a flac file like in the pic below (this one is hard coded).
I ripped the cover with the function getCoverFlac from my code, but the problem begins when I try to update this img with my imgSet fucntion, the image to load exist(can see it in the dir and can even be used hard coded), but the image wont appear in the Ttkinter window. I believe its receiving the right file name since it returns the name correctly:
name of cover to display:Shikao Suga - Yuudachi ('99 NHK Hall 0 Live).flacCover.jpg
so how can I fix this?
full code bellow:
import pygame
import tkinter as tkr
from tkinter.filedialog import askdirectory
from tkinter import *

from mutagen.flac import FLAC, Picture

from PIL import ImageTk, Image

pygame.init()
pygame.mixer.init()
def play():
pygame.mixer.music.load(play_list.get(tkr.ACTIVE))
#gets and set the var name
var.set(play_list.get(tkr.ACTIVE))
#gets the cover and sets the the img that will be in panel
getThecover = getCoverFlac(play_list.get(tkr.ACTIVE))
imgSet(getThecover)

#this fucntion extracts the image from the flac file and saves it in the dir where the flac file is.
flacObj = FLAC(flac_file)
coverArt = flacObj.pictures
coverName = str(flac_file)+"Cover.jpg"
if os.path.isfile(coverName):
print(coverName+" already exists")
else:
for img in coverArt:
if img.type == 3:
with open(coverName, "wb") as f:
f.write(img.data)
print(coverName+" created and saved")
#img.show()
return coverName
def imgSet(var):
#sets the global var "img" to var
global img
print("name of cover to display:"+var)
resizeImg(var)
img = ImageTk.PhotoImage(Image.open(var))
def resizeImg(imgName):
basewidth = 300
img = Image.open(imgName)
wpercent = (basewidth/float(img.size[0]))
hsize = int((float(img.size[1])*float(wpercent)))
img = img.resize((basewidth,hsize), Image.ANTIALIAS)
img.save(imgName)
Button1 = tkr.Button(music_player, width=5, height=3, font="Helvetica 12 bold", text="PLAY", command=play, bg="blue", fg="white")
Button2 = tkr.Button(music_player, width=5, height=3, font="Helvetica 12 bold", text="STOP", command=stop, bg="red", fg="white")

Button4 = tkr.Button(music_player, width=5, height=3, font="Helvetica 12 bold", text="UNPAUSE", command=unpause, bg="orange", fg="white")
Button5 = tkr.Button(music_player, width=5, height=3, font="Helvetica 12 bold", text="Music Dir", command=selectDir, bg="green", fg="white")
var = tkr.StringVar()
song_title = tkr.Label(music_player, font="Helvetica 12 bold", textvariable=var)
resizeImg('Haddaway - What Is Love (70 Mix).flacCover.jpg')
img = ImageTk.PhotoImage(Image.open('Haddaway - What Is Love (70 Mix).flacCover.jpg'))
panel = tkr.Label(music_player, image = img, justify=CENTER)
song_title.pack()
panel.pack(fill="x")
Button1.pack(fill="x")
Button2.pack(fill="x")
Button3.pack(fill="x")
Button4.pack(fill="x")
Button5.pack(fill="x")
play_list.pack(fill="both", expand="yes")
music_player.mainloop()

You just update the global variable img inside imageSet(), but forget to update the image of the label using panel.config(image=img):
def imgSet(var):
#sets the global var "img" to var
global img
print("name of cover to display:"+var)
resizeImg(var)
img = ImageTk.PhotoImage(Image.open(var))
panel.config(image=img) # update image of label "panel"

How can I return a variable from a function that is opening a file using filedialog after selecting a tkinter button?

All of the tutorials I have seen deomonstrate the tkinter filedialog.askopenfilename function by only using the information collected within the function that is linked to the tkinter button. I can pass information in the function, but I would like to pass variables (filepath, images, etc.) outside the function and have them update variables in my GUI.
I have commented out the location I would like to call the variables in main_gui_setup function below. Any help will be appreciated, as it has been very demoralizing not being able to open a file. If this problem persists, my future as a programmer may be limited to creating tic-tac-toe games or instructional videos for Youtube.

You aren't thinking of event driven programming correctly. In event driven programming you have callbacks to the functions you defined. Let's look at your code:
def get_path(self):
...
self.path_label = ...
...
def main_gui_setup(self):
main_win = ttk.Frame(self.root)
main_win.pack()
open = ttk.Button(main_win, text="Open", width=10, command=self.get_path)
open.pack()
# Problematic code:
# main_label = ttk.Label(main_win, self.path_label)
# main_label.pack()
When main_gui_setup is called it creates a frame and a button inside it. When the button is clicked it calls get_path which sets up the path_label variable. The problem that you were facing is that that as soon as you create your button (without waiting for the button to be pressed), you create the label called main_label.
For a simple fix to your problem try this:
def get_path(self):
...
self.file_path = ...
self.path_label = ...
...
def button_callback(self, main_win):
# set up
self.get_path()
# My guess is that you wanted `self.file_path` here instead of `self.path_label`
main_label = ttk.Label(main_win, self.file_path)
main_label.pack()
def main_gui_setup(self):
main_win = ttk.Frame(self.root)
main_win.pack()
# I am using a lambda and passing in `main_win` because you haven't
# assigned it to `self` using `self.main_win = ...`
open = ttk.Button(main_win, text="Open", width=10, command=lambda: self.button_callback(main_win))
open.pack()

I am still confused by what You are trying to accomplish:
from tkinter import Tk, Button, Label, filedialog
class MainWindow(Tk):
def __init__(self):
Tk.__init__(self)
self.open_file_btn = Button(self, text='Open', command=self.open_file)
self.open_file_btn.pack()
self.file_name = None
def open_file(self):
self.file_name = filedialog.askopenfilename()
Label(self, text=self.file_name).pack()
root = MainWindow()
root.mainloop()
I will explain what will happen here! (You can change the .askopenfilename() attributes obviously).
When the program opens the filedialog and You select a file, that file name will now get assigned to self.file_name and that variable can be used anywhere in the class.
also from what I have seen You should learn more about classes and PEP 8

How to print values in GUI from image in python?

I'm new in GUI developing.Here i'hv created two GUI, one for taking photo and another for showing features.so,i'hv used two functions.but i don't know some things.Now i need two kinds of help from you.
1)what is the command for printing float value in GUI(not on console)?
2)How to calculate the value of mean,variance ,s.d. etc from a image and how to pass those values from one function to another function?

Okay, I took some more time to look into it.
Concerning the calculation of the values, your previous question did that correct, however the variables needed to be accessible globally. Concerning the displaying of a text, you have to add a tkinter text widget. If you want to add more calculated values, just google for numpy + 'value your want'.
I've taken your code and created a working example, see the code below. Note that I removed some stuff that wasn't neede for the example, so copy the lines you need to your own code. Also check out this reference for the text widget.
Result:
Code:
Note: I created 2 text widgets deliberately, to show 2 ways of implementing multiple texts
import tkinter as tk
from tkinter.filedialog import askopenfilename
import shutil
import os
from PIL import Image, ImageTk
window = tk.Tk()
window.title(" ")
window.geometry("500x510")
window.configure(background ="lightgreen")
title = tk.Label(text="Click below to choose picture for testing disease....", background = "lightgreen", fg="Brown", font=("", 15))
title.grid()
def feature():
window.destroy()
window1 = tk.Tk()
window1.title(" ")
### create a text widget, place it in window1 and insert the text
width_txt = tk.Text(window1, height=2, width=30, fg="RED", background = "lightgreen", relief="flat")
width_txt.grid(column=0, row=0)
width_txt.insert(tk.END, "Width: " + str(width))
height_txt = tk.Text(window1, height=2, width=30, fg="RED", background = "lightgreen", relief="flat")
height_txt.grid(column=0, row=1)
height_txt.insert(tk.END, "Height: " + str(height) + "\nMean: " + str(mean))
window1.geometry("650x510")
window1.configure(background="lightgreen")
def openphoto():
### this line makes the variables accessible everywhere
global width,height, mean
import numpy as np
fileName = askopenfilename(initialdir='', title='Select image for analysis ',
filetypes=[('image files', '.jpg')])
photo = Image.open(fileName)
#### calculate values
height = np.size(photo, 0)
width = np.size(photo, 1)
mean = np.mean(photo)
render = ImageTk.PhotoImage(photo)
img = tk.Label(image=render, height="250", width="500")
img.image = render
img.place(x=0, y=0)
img.grid(column=0, row=1, padx=10, pady = 10)
title.destroy()
button1.destroy()
button2 = tk.Button(text="Analyse Image", command=feature)
button2.grid(column=0, row=2, padx=10, pady = 10)
button1 = tk.Button(text="Get Photo", command = openphoto)
button1.grid(column=0, row=1, padx=10, pady = 10)
window.mainloop()
