• School projects. A student may use any image for a school project, all I ask is that I get a credit.
• Positionals/comps. Professional designers can use any image as a positional but if the project goes ahead please contact me regarding payment, provision of a print, high quality scan etc.
• Wallpaper. For personal use on computers. If the computer happens to be at work that's OK, but if my images are loaded onto 500 corporate machines, then I think it's fair to pay me for the use.

The fact is that I quite often let people use my images for all sorts of non-profit reasons, just and ask. However if you're making money from them, then I want some of it
