I have a deal setup with the admins here - any image of mine that doesn't involve any copyrighted characters - I'll sell to you for a flat fee of $49. It'll be 100% yours and I'll remove it from the site. Use it commercially, resell it, you can do anything with it. I can't remove it from other places that scrape this site, so that's all on your end.
TO BUY: email firstname.lastname@example.org with the image, and they'll work out the details.
