I just looked up for some stock photo market places & I could not believe my eyes at what some people are earning from taking stock photos & selling them royalty free. It is in the thousands of dollars per month! The highest claimed was above $9000 per month. Although it may take years to build up a professional set of skills in photography, I am confident that many of us including myself are able to cash in on some good photo sales along the way.
