I seached this forum on keywords associated with my topic and no hits. Perhaps there are more appropriate sources of recommendations, and if so inform me. I have downloaded a few trial/evaluation versions of utilities that search for duplicate images; JPGs . Some claim that they will find visually similar images in addition to those that are binarily identical. I have tried to use Running Man Software's DIF, and some others. I don't mind paying a reasonable price for a good tool. I have not found one that has a really good interface and functionality that suits me. Where should I be looking?
