deleting duplicate pictures

[Martin Burnicki]

Hi,

following this thread, a question comes into my mind:

If DK has detected duplicate images, which are the criteria to determine 
which instance is the original image and which ones are copies?

I think this is important to know to avoid that original instances are 
deleted when the "Remove duplicate" button is clicked.
(Yet, I've never tried this feature)
