the header template.
We did it like this, and it seemed to work OK. Replacing the code within the logo table <td> statement
Code:
<a name="top"></a>
<style>
.bannertable {height:100px; width:100%; padding:0px; margin:0px;}
.bannerleft {text-align:left; vertical-align:bottom; width:147px;height:100px; padding:0px; margin:0px; background:#DE2418;}
no-repeat #DE2418; height:72px; width:91px; position:absolute; top:18px; left:230px;}
.bannerright {background: url(http://www.redandwhiteonline.com/images/Forum%20Header%20Right.gif) right top no-repeat #DE2418; height:100px; width:100%;padding:0px; margin:0px; border-bottom:1px solid #F1B0AD;}
</style>
<div align="center">
<table border="0" cellpadding="0" cellspacing="0" class="bannertable">
<tr>
<td class="bannerleft"><a href="http://www.redandwhiteonline.com/BOTW.html"><img src="http://www.redandwhiteonline.com/images/Banner%20of%20the%20week.gif" height="100" border="0" alt="Banner click-through disabled" /></a></td>
<td class="bannerright">
</td>
</tr>
</table>
</div>
Hope it helps.
