I needed a simple gallery solution with following features:
- bulk upload of pictures and descriptions (captions)
- sub-galleries structure
- customizable layout
- no browser-plugin required (flash & co)
- and a few more minor things.
Commercial or free, that wasn't the main point.
I've checked out quite a few solutions, but only SPGM gives me exactly what I need! So thanks a lot for your efforts! Donation will follow...
