If you select *all* then of course *all* selected will be deleted.
Besides, how should it know what you consider the original of two identical duplicates.

Ok, but isn't there anyway to select only duplicates?

If you have them in the mysql database already. Then you can


select (T1.name, t1.md5sum where ( t1.md5sum=t2.md5sum )) and ( T1.second_field <> T2.second_field ))

from  table_one T1 table_one T2 

You'll have to check the syntax, but it can be done

The mysql 5.7 manual on-line has a fine example of this.

I have a similar 'issue'. I have a lot of duplicates and the only thing I want to do is merge them. I don't care which is the original. In my eyes they are both copy and both original. Only thing I want is to be left with one of the two. I don't care in which album they are, or will be. Is there any way to do this easily? Manually selecting 1000+ images is not my hobby :-P.

Thanks BigIsland, so I guess your answer is also that there is no way of doing this within Piwigo. It would have been a great feature.
