All of these photographs are available at the DKos Photo Coop.
Check out the Coop's Groups Page for more information on the coop, as well as how to use it and how to contribute.
For a brief history, this is a project that was envisioned by Meteor Blades who asked me to help him set it up. It went live about a year ago and we now have over 75 contributors who've uploaded over 750 photos to date.
I haven't been doing as much promoting of it as I would like, simply because my real life duties are keeping me so busy. That said, it's a cooperative effort, so the more folks use the photos, the more widely the word will spread.
