WIthout looking at all your code for the style. It's hard to tell. I'll go to your site in your profile and take a peak.
Okay, try this for me:
In your header template. Add this code to the very bottom.
HTML Code:
<table width="892" align="center" border="0" cellpadding="0" cellspacing="0">
<tr>
<td width="16" align="left" valign="top" style="background-image:url(images/styles/alturas8/misc/table_left.png)"> </td>
<td>
In your footer template search for: (thats not a type-o)
Above that add this:
HTML Code:
</td>
<td width="16" align="left" valign="top" style="background-image:url(images/styles/alturas8/misc/table_right.png)"> </td>
</table>
