My bad. Didnt know you had that. Just change the header again:
Code:
<!-- logo -->
<a name="top"></a>
<table border="0" width="100%" cellpadding="0" cellspacing="0" align="center">
<tr>
<td align="center" valign="top"><img src="http://www.somtour.net/forums/images/styles/silverwhite/misc/logo.jpg" border="0" alt=""/></td>
</tr>
</table>
<!-- /logo -->
<!-- content table -->
$spacer_open
$_phpinclude_output
$ad_location[ad_header_end]
For your reference, and knowledge. I made the image source, a direct link to the image.
