jAlbum

Excellent product with good support

jAlbum is a very versatile product, which works well and is highly configurable. I have used the free version, with the odd donation until recently, but decided to go for an upgrade to enable removal of the increasingly obtrusive (but not unreasonable) advertising.

For those of us with limited (or no) web design skills, it enables web photo albums to be set up quickly and extremely easily - a lovely piece of software.
