Sorry my mind is blanking right now, but what is that site that you use for seeing massive game pictures that you can use for renders? I've seen it referenced here before, thanks for the help.
Gamewallpapers are pretty bad quality if you aren't a premium member. I mostly just download stock packs on PR and here on GR.
Game Wallpapers and Gamerenders only obviously ^_^ And yeah you aren't allowed to render from CERTAIN websites.
