To update the image of a tkinter label widget, you can follow these steps:

  1. Load the new image that you want to update the label with using the PhotoImage class in tkinter.
  2. Configure the label widget with the new image using the config method and passing in the image parameter with the new image object.
  3. Update the label widget by calling the update_idletasks method to redraw the widget and display the new image.


Here is an example of how you can update the image of a label widget:

import tkinter as tk
from tkinter import PhotoImage

# Create a tkinter window
root = tk.Tk()

# Load the initial image
original_image = PhotoImage(file='image1.png')

# Create a label widget with the original image
label = tk.Label(root, image=original_image)
label.pack()

def update_image():
    # Load the new image
    new_image = PhotoImage(file='image2.png')
    
    # Update the label widget with the new image
    label.config(image=new_image)
    
    # Update the label widget to display the new image
    label.update_idletasks()

# Create a button to update the image
button = tk.Button(root, text='Update Image', command=update_image)
button.pack()

# Run the tkinter main loop
root.mainloop()


This code creates a tkinter window with a label widget displaying an initial image. When the "Update Image" button is clicked, the label widget updates with a new image.
