JAlbum will thumbnail all your images for you, and can then even FTP them to your website. You should take a look as it's pretty much a total solution... http://jalbum.net/quickstart.jsp
Antonye's spot on with the JAlbum software, I checked out loads of others last weekend but JAlbum is way better than anything else i tried. Adding the filters is a bit of a pain as you cant cut and paste the text in. It's all case sensitive too, but you only have to type stuff in once.
