Splash Art Wallpapers?

Hey, I know Riot has a page where you can get the basic skin splash arts as wallpapers for your computer, but I was wondering if there would be some way to get the Splash Arts for skins added to this? I enjoy playing this game, and I have a fair amount of skins (many of my friends would say too many skins) and I like repping my favorites on my computer. I've been able to find some, but they're usually some weird size, colored strangely, edited or just plain lower quality than the official Riot ones. They also don't have that snazzy official "League of Legends" emblem. I would really love to have an official way to show off my favorite skin splash arts. I might be alone, but I really love some of the art, especially some of the newer ones that look all cohesive and dynamic and stuff.
