MG2, or MiniGal v2, is currently in beta release stages but looks quality. It's very well laid out, doesn't need a database, it's fast and of course, it's free. A highly recommendable way to run a simple, clean PHP image gallery. There is support for plugins although none are available at time of writing, however there are loads of language packs and templates on offer. The original MiniGal code is also on the download page for those that want it.
