Looking for Wallpaper help!

So the Mecha Zero Sion page is up, and at the bottom are several cool as hell wallpapers are available for download. Problem is, I have an odd monitor resolution. I really want to get the Designation: Mecha Zero Sion and Designation: Charged For War wallpapers. Could anyone PLEASE help me get my hands on these at 1366x768 resolution? Any and all help would be appreciated to no end!
