I was looking around on that site, about to upload images that I saved for the web. What I noticed was this requirement that said you couldn’t have watermarks on or borders around your images.  I went on and uploaded an image.  Right after that, I saw they needed to be approved. Right above the image, it showed the maximum size YOUR image could be if it were printed. That seemed to click with why they didn’t want borders or signatures. So they’re selling the images you upload too?
