Unfortunately, I don't know the package ImageTk you're using. But at tk 
level, images are mutable without problem. It seems however that the tcl 
commands allowing to read an existing image from a file are not exposed 
at Tkinter level. But it is still possible to send the command to the 
underlying tcl interpreter to do it:

from Tkinter import *
root = Tk()
image = PhotoImage(file='f1.gif')
label = Label(root, image=image)
## When you want to change the image:
root.tk.call(image, 'read', 'f2.gif', '-shrink')

This will only work with image formats supported in the tcl/tk core, 
which are basically only GIF so far.

BTW, I don't understand why you talk about label.bindŠ If you need to do 
anything when the label is clicked, you have to make a binding on the 
label whatever it is.

HTH anyway.
