AllSync & AllDup

Thanks very much therube (glad the pics brought back happy memories for you too) and Admin (would not have known to use mHash).

Thanks, here is a link to a few dups that don't get found, even when they are in the same folder.

I just started using AllDup and it seemed to work but now when I compare two folders with known dups, it does not find any.
It looks like some of the pics are reversed, but this should not matter? I tried with various orientation options on and off.
I could send two of the dups to check?
