Somehow to compare slides

[rmilyard 4]

I would be nice but not sure if can do it but some way to compare all your slides.  I am working on redoing my Kodi and Movie Poster but finding it very hard to know what I have and what need to download still.

personally I keep each set in it's own folder to avoid this type of issue

. Because people could rename files differently you would probably have to do something like a crc or sha hash on each picture and compare it to some currently non-existant database of hashes.
