I have over there a folder for textures ... free textures for 3D modeling, brushes, scrapbooking, or anything else people want to use them for ... which I put into the "public domain". There are a few new ones in there now ... nothing stays posted "forever".

I also post a lot of sky photos ... and some of the moon ... those people are welcome to use "responsibly". I do not require credits but still, "the aliens are telepathic be careful" [cough, cough]. As there is no way I can cover all bases, if people see something they want to repost elsewhere [like facebook, etc.] yes they may.

And there's the occasional bird or something else that stayed still long enough to have its picture taken ;-)
