Hi!

First of all thank you for this great software! I tried many others but stopped my search when I discovered Piwigo because it has all features I need and it works!

I have just one question (I didn't find answer anywhere).

I would like to ask you if it's possible to generate hashes (md5sum) for files uploaded by ftp (and syncing afterwards) and not by using upload page.
I'm hosting server with IIS10 (actually it's just an old PC :-) and copying pictures directly to disk so checksums are not created (I checked MySQL database and `piwigo_images`.`md5sum`are empty).

I suppose the hash is generated only during upload. Is there any option to generate hash during syncing? (Or some other way?)

Thank you!
