I was very lazy with this snippet. I almost decided not to publish it. But then do it anyway. Things that could be improved - more explanation about the code - redraw() - redraw also scrollable to more than 16 images - changing directory to E:\ or sub-directory (also display how many images are there in the sub-dir) After thinking how much is left to be done, I stop. ^_^ Well, I really wish there were a good, free gallery app.

I also forget 3) open image in the python app not with the gallery (it's better) and allowing me to zoom !

hello , Very cool indeed but there are missing some things ... 1) After opening a thumbnail and I go back to python gallery , all thumbnails disapeared (I suspect not using callback_redraw in Canvas widget !) 2) If I have more than 16 thumbnails , I always see image name in the title but not the frame cursor ! (thumbnails would have to scroll to show hidden others)
