There is a way around the file size limitation by having the wiki's background point directly to the file instead of trying to upload the picture in the Theme Designer. I think it's in the Common.js file.

The picture you created, Alfa9delta, has the right dimensions to fit widescreen monitors and you have the side elements placed correctly. I will need to check how much transparency to use so the center logo shows up but doesn't obscure the text of the page being displayed.
