Selling Photographs

I heard a very interesting podcast tonight while I was driving in my truck. That discussion revolved around the differences between the different ways to market and sell images. Mainly, they were discussing the difference between “rights managed,” and “royalty free” pricing.

Have any of you had any success selling photographs?

A majority of my photo sales are with parents who want the action images I captured in a baseball game, a school musical, or some other event. This is much different from selling photographs to magazines or other venues. I also sell wildlife and landscape photos occasionally. But I am curious to how you market and sell your photos. What works for you? Are any of you into micro-stock photography, for example, selling photos on iStockPhoto or some company like that? What works? What do you find frustrating?
