If you have a reasonably good camera and some good lenses you can make money by submitting your pics to microstock sites. I've started doing this with pics I've already taken. Things you have to consider: You need model releases if you take a pic of anyone and/or property releases for pictures of buildings...unless they are sold as editorial pictures(for news ), rules are clearly explained on sites.
Also some sites like 'shutterstock' are very picky when it comes to quality. Expect a LOT of pics rejected for inexplicable reasons. Still if you got a good pic hanging about your hard drive it might be worth uploading. It's free and you could earn some money.
