iStockphoto.com - royalty free stock photography community
This site has an interesting model; you (as a photographer) upload images for others to download and use. They pay 50 cents per image downloaded, and you get a 10 cent credit.
So, if you submit a picture, you get a ‘free’ image for every five people that download it. You can cash out your credits if the amount earned passes $100 (that’s what, 1000 downloads? Not bad.)
