Two solutions come to mind:
- specifying a width and a height for the button; a bit awkward, since the unit 
taken for the dimensions depends on what is displayed in the button (pixels for 
an image; characters for text). And configuring the button size when nothing is 
displayed in it seems to take dimensions in characters, which is not suitable 
for what you want to do.
- create an empty image of the same size of the existing one and set this image 
for the button when it should be empty. Example:

from Tkinter import *
root = Tk()
img = PhotoImage(width=50, height=50)
Button(root, image=img).pack()
root.mainloop()

This may be the best solution for what you want to do.
