Another sliver question (but different)

I am making my first webpage for my wallpapers. My generic page looks like black and blue clouds with different filters used. There are two sets of lines on the top and bottom roughly 62 pixles from the top and bottom. Creating the slivers for the left and right was no problem. Haven't started the top and bottom yet. Here is where I am lost of what to do. I would like the main background to be the center and have it sliver out to the left, right, top and bottom for different screen resolutions and different web page sizes. Here is the question: What do you think the best solution is for the corners?
