how to display blob as image in a table in tkinter python

I am trying to insert and retrieve image from MySQL database.I have inserted the image as BLOB (longblob). When I am able to display it using image.show() but I want the image to be displayed in a table.
I used treeview for this purpose. But my table shows only BLOB objects. It doesn't show any image.
This is my code.

my_label = Label(root, text=root.filename).pack()
my_image = ImageTk.PhotoImage(Image.open(root.filename))
path = root.filename
id1 = id.get()
person = mysql.connector.connect(host="localhost", user="root", password="", database="image")
cursor_variable = person.cursor()
thedata = open(root.filename, 'rb').read()
sql = "INSERT INTO image_db (id,data) VALUES ('" + id1 + "',%s)"
cursor_variable.execute(sql, (thedata,))
person.commit()
person.close()

Any help is appreciated.

I have modified your display_Table():
set the rowheight of treeview to 50
set width of column "#0" to 100
resize the retrieved image to fit the treeview cell
def display_Table():
...
style = ttk.Style(root)
style.theme_use("winnative")
style.configure(".", font=("Helvetica", 11))
style.configure("Treeview.Heading", font=("Helvetica", 11, "bold"))
style.configure("Treeview", rowheight=50) # set row height
my_tree['columns'] = ("id",)
my_tree.column("#0", width=100, stretch='NO') # set width
my_tree.column("id", width=100, anchor='w')
my_tree.heading("#0", anchor='w', text='Image')
my_tree.heading("id", anchor='w', text="Id")
count = 0
my_tree.imglist = []
for record in cursor_variable:
img = Image.open(io.BytesIO(record[1]))
img.thumbnail((50,50)) # resize the image to desired size
img = ImageTk.PhotoImage(img)
my_tree.insert(parent="", index="end", iid=count,
image=img, values=(record[0],)) # use "image" option for the image
my_tree.imglist.append(img) # save the image reference
count += 1
Note that I have used a list to hold the image references to avoid garbage collection.
The output:

Sqlite3 Accessing a specific record from a database from a different class and putting it into a tkinter entrybox

The function of this code is that it displays the list of records in a database with one of the fields being a button. When this button is clicked it brings the user to a new frame which displays the account information for that record.
The record information is displayed in the Record class as dat[0] and dat[1] and I have had problems with initializing this in the second class, I do not know how I would get this information to appear on the second screen.
Thanks for any help.

Have you tried merging the two classes together ?

if you can push values from database you only need make a .insert on Entrybox
maybe like this
tkEntry = Entry( master)
tkEntry.pack() # .grid or .place, don't make this in obj create
tkEntry.insert( 0, dat[0] ) # 0 is the index and dat[0] is your value

Opening images from 2 folders and displaying them simultaneously in python

I would like to open images from 2 different folders and display them next to each other , also have a button " Next" to be able to move to the next pair of images.
The images paths are stored in a txt file , so lets say open the first image and the second image and when I click next , 3rd and 4th image and so on
I am new to python and this is what I found so far to read an image
from Tkinter import *
from PIL import ImageTk, Image
import os
root = Tk()
img = ImageTk.PhotoImage(Image.open("path.ppm"))
panel = Label(root, image = img)
panel.pack(side = "bottom", fill = "both", expand = "yes")
root.mainloop()
But i can't figure how to open 2 images simultaneously and add the next button

Here is a working example of what you ask:
from tkinter import *
def UpdateImg ( ):
global img1, img2
img1 = PhotoImage(file=ImgFiles[Cur])
img2 = PhotoImage(file=ImgFiles[Cur+1])
LblImg1.configure(image = img1, text=ImgFiles[Cur])
LblImg2.configure(image = img2, text=ImgFiles[Cur+1] )
def BtnNext( ):
global Cur
if Cur < len(ImgFiles)-2:
Cur = Cur + 2
UpdateImg ( )
def BtnPrev( ):
global Cur
if Cur > 1:
Cur = Cur - 2
UpdateImg ( )
fp = open("ImgFilesSrc.txt", "r")
ImgFiles = fp.read().split('\n')
fp.close()
Cur = 0
img1 = img2 = ''
root = Tk()
#Create the main Frame -----------------------------------------------------------------
FrmMain = Frame(root)
LblImg1 = Label(FrmMain, text = "Picture 1", anchor=W, width=120, bg="light sky blue")
LblImg2 = Label(FrmMain, text = "Picture 2", anchor=W, width=120, bg="light sky blue")
BtnPrev = Button(FrmMain, text=" < ", width=10, command=BtnPrev)
BtnNext = Button(FrmMain, text=" > ", width=10, command=BtnNext)
LblImg1.grid (row=2, rowspan = 3, column=1, columnspan=3);
LblImg2.grid (row=2, rowspan = 3, column=4, columnspan=3);
BtnPrev.grid (row=5, column=2); BtnNext.grid(row=5, column=4)
FrmMain.pack(side=TOP, fill=X)

python error run from cmd

For my coursework i am doing a booking system which uses some tree views.

when i was copyign and pasting the rest of my code that i forgot to put in the original post i found that it only stops working if i open it through the student menu(separate peice of code) but it works if i dont go through the menu

You must call mainloop() on the root window so that your program can process events.

You create LabelFrames in the parent called root, but root does not exist. To correct it pass master to the function, which receives it as root
class Application():
""" Binary to Decimal """
def __init__(self, master):
""" Initialize the frame. """
self.create_GUI(master)
def create_GUI(self, root):
frame1 = tk.LabelFrame(root, text="frame1", width=300, height=130, bd=5)

Hi, i am trying to build a discussion Bot.
When I execute the code, the question in the input field and the answer get displayed correctly.
The problem is after entering the next sentence, the previous question/answer gets removed. Here is an example:
Hello Bot
Hello User
(then the text disappears)
How are you
Fine thank you
What i want :
Hello Bot
Hello User
(then the text stays in the frame)
How are you
Fine thank you

The issue occurs in line -
user_says.set(input_get + "\n\n")
ia_says.set(ia_answers)
You are replace users_says.set() and ia_says.set() resets the complete Labels , with the new value. Instead you should get the old value and append the new value to it and set it back, Example -
user_says.set(user_says.get() + input_get + "\n")
ia_says.set(ia_says.get() + ia_answers + "\n")
Or you can also create a new label for each new event and add it to the LabelFrame . Example -
from tkinter import *
window = Tk()
ia_answers= "trolol\n"
input_frame = LabelFrame(window, text="User :", borderwidth=4)
input_frame.pack(fill=BOTH, side=BOTTOM)
input_user = StringVar()

ia_frame.pack(fill=BOTH, side=TOP)

bg="white")
