I occasionally submit photos to stock photo agencies, mostly to iStockphoto. You don’t make a lot of money, but you do get some income. One of the downsides is that you rarely know where your photo is used. So, imagine my surprise when I opened the Yahoo! page and there was my photo of Phoenix used to illustrate a Yahoo! news story about home prices.
You can see the photo on the Craig Stocks gallery on iStockphoto and other Getty stock sites.
