I thought these might be handy if you are looking for a web album software to download onto a website....
Web Album Creator YoPoW
Web Album Generator - ornj.net
AnvSoft Web Album Maker-Free Web Photo Album and Online Photo Album Software.
This is my personnel favourite
JAlbum - the free web photo album software and photo gallery software
My website has mainly used the jalbum...
e.g.
Flora
There is still plenty out there free, but these I know.
Hope this is useful to you.
