Theme background help

[Nemesis]

will be in your css, im looking at it i think your #wrapper should say something like height: 100%; that way if the site takes up more than one monitor length page it will continue to add the background images. again thats

#wrapper { height: 100%;
background: url(chibi-blue-images/chibi-blue-bg.png) center top no-repeat;
}

its something like that. hope that's right.
