[Trisquel-users] Re : Can Anybody ?

If the pictures are exactly the same, any file duplicate detector will do the  
job, e.g., rdfind or fdupes (both are in Trisquel's repository). There exits  
some graphical interface to such commands (and others). FSlint, for instance,  
is in Trisquel's repositories.

If the images were modified (e.g., resized), take a look at findimagedupes,  
which is in Trisquel's repository too.
