Tkinter Button image option

[Elaine Jackson]

When I try to put an image onto a Tkinter button, I get a message that says the
image in question "doesn't exist" (it does, though). One of the references I
looked at said that Tkinter has to be "configured for" the Python Imaging
Library in order for the 'image' option to work. I've got the PIL, but as for
"configuration", I don't know. Maybe I need to reinstall Tcl/Tk? If anyone can
point me to the appropriate resource, I'd be very much obliged.
Peace
