on 500.PX, there is a section that tells you how you can protect your images. You can choose to let others adapt your work for commercial gain..
or adapt it as long as they do not stand to make any commercial gain from it
As well as a range of other licences that allow you to tailor what you want people to be able to do with your work, and to protect you from use of your images against your will.
