I see in some wikis (e.g Elders Scroll Wiki) that the background images could be as wide like a full 'wallpaper' size. Usually, there's a limit to how big the file and image size isn't it? Is this property tweaked in the CSS area to allow that? The quality of the images looks quite decent for a background ~ no rough areas or blurry views ~ it's visually clear.
Thx for your replies and help!
