Navbar table backgrounds

[Club3G]

I'm trying to add a simple background to the navbar. Here's a code snippet:

<td background="http://www.sevenstring.org/forum/images/navbar_backing.jpg" class="vbmenu_control"><a href="usercp.php$session[sessionurl_q]">$vbphrase[user_cp]</a></td>

However, the background isn't showing up. What am I missing? The image is fine:



It's a good thing I can answer my own questions most of the time, because 9 out of 10 nobody else does. :\

class="vbmenu_control"

^ Had to strip that from the tag.
