In searching for inexpensive stock photography for a comp, we ran across this website called stock.xchng. It's basically a community where members can share stock photography, for the most part free. This is what they said on their website:
"SXC was launched in February 2001, as an alternative for expensive stock photography. The idea was to create a site where creative people could exchange their photos for inspiration or work. In about two years the site evolved into this massive community you see now - there are over 1.500.000 registered users and more than 350.000 photos online!" (courtesy of stock.xchng)
It did have some decent photography on there so it was worthy of bookmarking. In order to use it, you have to sign up and you'll be a part of a community where you can also socialize. It might be worth checking out if you're in need of some free photography.
