basically everything I have up here, did you need high res or something?
I wouldn't use the 2nd row, 3rd column picture as that is a modified scan from a Choose Your Own Adventure Book, and the 3d Rivers artwork (3rd row, 2nd column) is from searching Google Images for a company that makes cat trees. Also some of the album art is AI back when it got sketchier results and not so generic and bad. But a lot of it is just fractal art which obviously has no copyright issues
oh yeah also 1st row, last column is a Louis Wain sculpture, so I wouldn't use that either
