I am looking through Wikimedia, but I'm not sure how the licenses are going to pertain here. I have no intent to break any of them, but in the end, I intend to use them as part of a larger collage (a mosaic) that is going to be printed out and placed on a wall in all likelihood. It seems that I need to attribute the pictures, but how exactly?
I am truly ignorant here, I have to admit :-(
Still, I love the images!
I have looked at creativecommons.org, but when I search for images there, it seems they in turn search other common image sites for it... some sort of image meta search engine?
