Having recently added my own copyright widget photo's to my website i have now been asked by a voluntary organisation for use of one of my pictures. I said it would be ok and just asked for a credit back to my site. The pictures of the site contain my copyright logo and i offered to let them have one without the logo but now im wondering how this should be handled. If i do that then the picture could be used free from there site without that logo by someone else. Anyone have experience in how this sort of thing should be handled?
Thanks.
