No problem. Actually, the original idea didn't include a bg image at all, but it's not that big, just tiled. I host a good number of sites, both paid for, and as a favor. One of them is an image site (
http://starletrealm.com) and has frequent large uploads/downloads at peak times. The owner is looking for a more dedicated solution though, so once that's off, the network will be back to it's normal self.
