  == Public domain ==  Apparently, you release your (fine) work into the public domain. I suppose you've already put some thought into it, but nonetheless, I wanted to suggest that you consider using a license which ensures that derivative works also remain free to use (e.g. Creative Commons Attribution Share Alike). Currently I think that anyone can take one of your images, fiddle with it a bit and then copyright it however they like, reducing the potential benefit to others. Thoughts?  ''''''
