Three options for you. All command-line. I've never used the first two, and never tried your problem with the third...
http://pdiff.sourceforge.net/ is in the Fedora repos as PerceptualDiff. It looks like it will mostly compare two images together. http://www.marengo-ltd.com/open_source/index.php jpegdiff looks like it's just source code. Imagemagick might be your tool: http://www.imagemagick.org/Usage/compare/#metrics the compare functions allow you to fingerprint images in different ways (similar to creating a hash code. You wind up with a value that 'describes' the image.) If you generate a couple of different values for each image, you should be able to make a simple database to lookup similar pictures (imagemagick states you would actually use it to eliminate different pictures, as getting the same fingerprints wouldn't prove the pictures were the same.) -- You received this message because you are subscribed to the Linux Users Group.
