Still some images are not displayed correctly; I have uploaded a little demo screenshot of what I mean to <http://klappnase.zexxo.net/Tkimg_vs_PIL.html>. The PIL image in this example looks a lot like a GIF image created with convert or some other utility from the original PNG, that is why I thought about the on-the-fly conversion into GIF. When I call Image.save() on the image returned by Image.open() the resulting image looks ok, so I guess the problem must be with the ImageTk.PhotoImage . Is there any way to avoid effects like these that I missed so far?
