That makes sense. If the buttons have the images on top then I can just press to keep or delete. Then the next pair can slide into place. Should go fast. Many thanks.
Just an update: I needed to use PIL to get my jpegs usable on widgets under tkinter. Then I took a pair of images (resized and merged them) and put the combined image on a button. So this idea is working in 2.7 and 3.5. I did need to resolve some name space collision. I think that PIL and tkinter were both trying to use "Image". Anyway, I may instead put my image on a label rather than a button and use plain buttons to decide whether to delete a duplicate. At this point I can hit a button to bring up the next image on a label (itself on a canvas) but there is a bit of 'lag' - maybe half a second I guess because of the resize.
