If you for example set and image as a background for a table, instead of alt
use title="My Image" in the table you have the background set for.
You can do the body background image, but it's kinda pointless!
If that's not the case, could I see an image of your website with a piece
of the HTML coding, so I can tell ya for sure.
"title" replaces "name" as W3C XHTML / HTML 4.01 standards
