CheeseCake Photoblog is a feature rich, buzzwords compliant photoblog software / application written in PHP using a MVC framework.
A photoblog is a chronological log of photography, usually from a single photographer. Each photo in the log has a date associated with it. When you’re looking at any photo in a photoblog, you can generally navigate directly to the next older or next newer photo. Photoblogs also tend to have archives that allow you to view all the photos sorted by date. (adapted from http://wiki.photoblogs.org/wiki/Photoblog_vs_Gallery )
