It's really great. I don't know anything about programming. Can you load two images and change them by pressing a mouse key?

you can change by pressing a mouse key using this mouse key.
if you change bind to , it will be work well.

<Button-1>        Button 1 is the leftmost button, button 2 is the middle button
                  (where available), and button 3 the rightmost button.

                  <Button-1>, <ButtonPress-1>, and <1> are all synonyms.

                  For mouse wheel support under Linux, use Button-4 (scroll
                  up) and Button-5 (scroll down)

@Dhesmok
And the easy way to load two image is make frame twice.
But it need some error handing about border of img list
