okay i need two background images.. one i want centered and fixed on the page.. the other i want tiled around the centered one.. how do i do that?

put the tiled one as the background of the BODY.
use css positioning to place the centered one in place.
problem is that it will not be fixed into place then.
if you want them both together, then use an image editing program, combine them into one image, then place that as your body background and fix it into place.
