To help protect people's privacy, many of the photos on Flickr are restricted. If you have a Flickr account (free, and associated with a Yahoo! account), have me add you as a contact and magically you'll be able to see all the photos.
In the past, I had a ghetto MySQL backed photo system. Although it was ok for organizing the few photos I originally had, it was mostly written so I could learn how to combined MySQL and php in webpages. I've now moved to using a Flickr account, which contains all the previous photos as well as new ones. Seriously, check it out! A tiny random sampling of my photos are shown below.
