Alright. I am going to be making a personal profile for myself, and I want to use a full-size background, probably 1920x1200 backgrounds. But I also have some slightly smaller ones that I want to include, and I was wondering how people that have done this deal with monitors that are larger than the wallpaper size... So how do they?
