I cannot for the life in me work out why this does not work. I am using TKinter to display an image in Python. The code I have written so far is shown here:
from tkinter import *
from tkinter import messagebox
def unlock():
root.withdraw()
def logout():
inside.destroy()
root.deiconify()
#######################
### ###
### unlock Form ###
### ###
#######################
inside = Tk()
inside.geometry("576x576")
inside.title("SAFE CRACKER")
# LABELS, Textboxes and Buttons
imageInside = PhotoImage(file = "images/inside.gif")
imageLabel = Label(inside,image = imageInside).grid(row =1, columnspan = 2)
label = Label(inside, text="Safe Cracker", font = ("Arial",16)).grid(row = 0, columnspan = 2)
exitButton = Button(inside, text = "Exit", width = 15, command = logout )
exitButton.grid(row = 3, column = 0,padx = 10, pady = 10)
#######################
### ###
### Main Form ###

#######################
root = Tk()
root.geometry("430x450")
root.title("SAFE CRACKER")
# LABELS, Textboxes and Buttons
label = Label(root, text="Safe Cracker", font = ("Arial",16)).grid(row = 0, columnspan = 2)
imageSafe = PhotoImage(file = "images/safe.gif")
imageLabel = Label(root,image = imageSafe).grid(row =1, columnspan = 2)
label = Label(root, text = "Enter the code", font = ("Arial",12)).grid(row = 2, column = 0)
unlockCode = Entry(root, width = 30)
unlockCode.grid(row = 2, column = 1,padx = 10, pady = 10)
exitButton = Button(root, text = "Exit", width = 15, command = exit).grid(row = 3, column = 0,padx = 10, pady = 10)
enterButton = Button(root, text = "Enter the VAULT", width = 15, command = unlock).grid(row = 3, column = 1,padx = 10, pady = 10)
The code doesn't do much at present, however it's something i'm working on. When I run the program it will display a picture of a safe (Great), and when I click the button it moves over to the next form.
image of safe working
On the new form the image, labels and buttons do not display, however, when the image code is removed it all works swimmingly.
Initially I thought about putting the root form within a function, however, whenever I place this code within a function it fails to load the image (ahhhh). Can these images not be placed within functions?
You need to keep a reference to the photo.
imageInside = PhotoImage(file = "images/inside.gif")
imageLabel = Label(inside,image = imageInside)
imageLabel.grid(row =1, columnspan = 2)
imageLabel.photo_ref = imageInside # keep a reference!
Thank you for your help.
I can confirm that this works, here's the code.

from tkinter import messagebox

root.withdraw()
def logout():
inside.destroy()
root.deiconify()

I started working with tkinter recently and I have the following problem, I need to make the check box bigger but that is only possible with adding an image. The problem is that whenever I add an image to a button it becomes unclickable and the image is not displayed, here is my source code (part of a bigger project). My goal is to display some information and let the user decide which option he gets to keep using the check button. Any help is appreciated.

I tried some options that I saw on the forum, in another file they worked fine but when I tried to implement it in the project itself the checkbutton is still unclickable and it doesn't display the images either. tkinter checkbutton different image I tried to replicate Bryan's answer, but no luck there. Also didn't receive any console error message.
As #furas pointed in the comments above, the problem got fixed with keeping the images as member variables of the class, also the button became clickable after removing the self.toggle(var) command from checkbutton
I have written the following code to get the user input. But I am not able to add a scrollbar to it. I want to place a vertical scrollbar because I am not able to view all the input labels on my screen.
I first tried:
v = Scrollbar(root, orient='vertical')
v.config(command=root.yview)
It gave me the following error:
File "/Users/aaditya/Desktop/Blender_software/Blender_algo_exp/testing.py", line 235, in <module>
label1.grid(row = 1, column = 0, padx = 10, pady = 10)

self.tk.call(
_tkinter.TclError: cannot use geometry manager grid inside . which already has slaves managed by pack
After that I tried the following:
myscroll = Scrollbar(root)
myscroll.pack(side = RIGHT, fill = Y)
Which resulted in the following error:
AttributeError: '_tkinter.tkapp' object has no attribute 'yview'
How can I fix this?
This is my entire code:

Pack and grid cannot be used at the same time. So since you called the pack for the scrollbar, you cannot manage the following widgets by grid anymore. An easy fix is to place the scrollbar with grid function instead. Apart from that, try using a function or class to make your code less lengthy because now it seems hard to read and purposeless.
the following is working first pass around. Select file/s, activate the view button and def, view files. all good.
When trying to select another file/s, during the selection process, the GUI closes abruptly.
I tried to figure out of the variable needs to be reset, but that did not change.
after all the imports:

i tried testing an entry widget outside the frame and the entry widget was able to work, is it because the frame f_alarm is not looping constantly in the background?
When someone clicks on your button which activates the pressed_enter() function, it will call that function again every time which will set the time to H:M and it will get that value as the set_time.get() is called immediately after.
You're also creating a new Entry every time the button is being clicked because you put alarm_entry = tk.Entry(clock, textvariable=set_time)
in there as well. You should only put the set_time.get inside of that button so that it gets the value that is currently filled in into the Entry. The other things like
set_time = tk.StringVar()
alarm_entry = tk.Entry(clock, textvariable=set_time)
set_time.set('H : M')
Should be put outside of that function so they don't get called every time someone clicks on the button.
I am trying to place an OptionMenu widget inside of a frame, which itself is inside of a notebook. From what I've found online, the code for doing this is roughly:
# add a drop down menu
hops = range(0,6)
self.selectedHop = StringVar(frame2)
self.selectedHop.set(hops[0])
self.hopOptions = OptionMenu(frame2, self.selectedHop, *hops)
self.hopOptions.grid(row=0, column=2, sticky=EW)
However, when I place this in my code in the code below (the chunk above is placed towards the bottom of it, and is labeled "PROBLEMATIC CODE..."), my app just freezes and I have to force quit it, and I have no error message to debug with. Any help would be appreciated.

This is your problem. You're packing a LabelFrame in frame2, and then trying to grid something in frame2. A given container can only use one of grid() or pack()- using both won't cause an error, but the two managers will negotiate on how to place things for the rest of your lifetime.
The solution is to make sure that a given container's children are either packed or gridded, but never both in the same container (though you could have a structure parent->child->grandchild, where child is packed in parent and grandchild is gridded in child).
