Lately I have heard a lot about stock photography websites. Photographers load their images and pictures onto a website. People can then pay the website to download pictures. For each time a photographers picture is downloaded that photographer gets some money. The pictures can be of anything in the world that does not infringe on someone else's work. A picture of a couch, a dog, the sky, a glass of wine will all be acceptable.
Shutterstock.com happens to be the website that I am going to try to get my pictures on. They pay 25 cents per download so if one of my photos gets downloaded 50 times I get $12.50. If I get a couple hundred pictures on the site and they get downloaded 50 times a month then the potential is huge. They do have an approval process where they evaluate 10 of your finest and approve or disapprove and then you get started. I am putting together my ten best right now so we will see how it goes. I will keep you updated.
