This question already has an answer here:
Is there any place with good sets of free jpgs or pngs for use in collages or just any work in general?
I see so many great collages and work in general with a lot of great images incorporated, but I just don't know where to get started doing so for myself. I mean yes you could obviously search through thousands of images for the right one to cut out, but is there any site where you can find pre-made sets of images? I found a few on Deviantart. I'm personally mostly looking for illustrations of any type to use in collages.
