I'm not exactly sure what the procedure is for making and posting wallpaper images, but as much as I love CSI:NY, having to view the same thirty photos over and over again is kind of..well...boring. So, I want to take images from the CSI:NY gallery on here (photos, icon, fan art sections) and make my own wallpaper. Is that OK or are there copyright issues that would forbid my posting them when I'm done? Mostly they will be collage-type wallpaper, but I was curious what everyone has to say on that.

P.S. FAQ didn't mention anything about copyright issues when it comes to contributing items to a spot.
