If you update the web-photo-publishing solution Gallery 2 to version 2.1 (http://gallery.menalto.com/), it will provide you with some cool, new functions.
E.g. it allows you to distribute RSS feeds of your photo galleries, like this one. The gallery shown in the RSS feed is powered by a Mac OS X Server driven Mac mini.
One of the other cool, new functions is the rating option. Your viewers can now rate your photos, which is great, if you want to know which photos might be good enough to be published elsewhere.
