    I'm looking for software that can go through my archives and find duplicate photos. I would like for it to: 1) Find duplicates in different folders. 2) Find the same picture with different names. 3) Find duplicates if the picture has been rotated. (I don't know if duplicate finders do this.) 4) Cost no money. Any suggestions? Thanks.

      The only one that I have experience of is Duplicate Finder[^] but I don't think that it does rotated images.

        Does it do dupes that are different sizes, or cropped from the original?

          Different sizes - Yes. Cropped, not sure but don't think so.

            There is an old program called DupDetector that is still the best I know for this. It works across one folder and all it's subfolders. It doesn't care about names, and is free. It can detect similar images, where the resolution has changed, or it's been cropped, or has been edited slightly, etc. I don't think it detects rotations. Supports jpg,bmp,png,tif,pcx,tga,wmf,emf,psp. It was developed by the person at http://www.prismaticsoftware.com, but that site has been shut down for a while now. The version I have is 3.1 dating from 2003. You can find it various places on the web by googling dupdetector, though most of them seem to be older versions and sometimes seem to have been repackaged (using a different installer). HTH

              Just right something that looks at file sizes, then compare the last 10 to 100 bytes and you should be good with any image.

                The latest Picassa 3.5 does that, also has nifty facial recognition, also free.

                    The first xxx bytes will contain file header information and are more likely to be identical than bytes in the data section.
