Thanks for replying, guys. I'll try to look further into embedding metadata into images (I think I barely understand it in HTML to start with) and read up the CC website. I don't imagine any of my creations would be as constructive as this and most other forums though. But it sure won't hurt trying ...

What does it really mean releasing an image on public domain, and how should one go about doing it? An additional subset of the first question I really want to know is if whatever the benefits of a public domain image are, if they're applied to anyone anywhere, universally, or only to specific count...
