Well, after looking at PinkShingami's thread, I got fed up with Ayu's sponsors not making their wallpapers widescreen, so I decided to do it myself! All it took was a little resizing and cropping and extending of backgrounds where needed. All of them are 1440x900, which is compatible with 1280x800, but if you need another size, let me know.
Keep in mind I won't be able to do ALL of the wallpapers, due to either image size or placement of the images ON the original wallpaper. I'm still working as we speak and thought I'd take a break to post what I've done so far, so if your favorite wallpaper isn't here yet, keep checking back.
Again, thanks to PinkShingami for uploading the original wallpapers.
