Sell stock photos

This is a good way to make money while pursuing a fun hobby. Since people search for stock photos by keyword, your work will be on the same playing field as everyone else’s, meaning you should submit any photo you think is decent. Once it has posted, your work is done, and while you won’t generally make much per sale, having a good number of photos can mean accumulating a nice monthly side income with virtually no upkeep. iStockphoto, ShutterStock, and Fotolia are a few good places to shop around.
