Is there a way to make pictures "clickable"? I'm willing to revise the Python or Glade code directly if needed (although I am just starting to learn). As an alternative, I've tried to use a Button, but there doesn't seem to be a way to put a picture on the Button? Under General it says "Label with optional image", but there doesn't seem to be an option to use an "optional image" -- only to use text. Guess I could try to add all of my images to the "Stock Button" images somehow, but I would prefer to just make pictures clickable.
