6 years on and this image is still being used a hell of a lot! People have said to me imagine if I'd chosen to distribute it through a paid stock photo site imagine the money I might have made. The image however was made simply to be used in my own and others work, so I'm happy that people can freely use it (albeit only non-commerically without permission).
If you would like to give me and token of thanks, I would point you to my Amazon wish list, where if you were so inclined you could send me a book![link]
