[Tkinter] How do I change an image dynamically

[moorthypnt]

Try this...

from tkinter import *
from tkinter import ttk

def TestLogic():
    stgImg = PhotoImage(file="Stage1.gif")
    label.configure(image=stgImg)
    label.image = stgImg

root = Tk()

root.geometry('1010x740+200+200')
 
stgImg = PhotoImage(file="Stage0.gif")
label=ttk.Label(root, image=stgImg)
label.place(x=400, y=400)
 
testBtn=ttk.Button(root, text="TEST", command=TestLogic)
testBtn.place(x=400, y=200)
root.mainloop()

It is working.

But what is the logic behind
"label.image = stgImg " this command.

Only this command makes it work. It is completely new addition when compared with text update.
