[Tutor] Update a button content on click

[ANKUR AGGARWAL]

hmmm... i got the point.
I applied it in image case.

b1=button(root,image=None,height=4,width=4,command=ok)

and then ok defination is as follows :
 def ok():
  b1["image"]=photo

now problem is that after clicking on the button, image is coming up like a
flash and then button becomes almost to zero size. I want to retain the
height=4,width=4 along with the image after clicking on the button. Image
size is smaller than the button size.
