center ad

[arcountryboy]

I added an ad banner for a new forum sponsor. I added the html code into the header template at the very end under "
$ad_location[ad_header_end]". The banner is to the left of the screen above the navbar and below my forum header pic. How can I center it?

Here is the header code.

PHP Code:

<!-- logo -->
<a name="top"></a>
<table border="0" width="$stylevar[outertablewidth]" cellpadding="0" cellspacing="0" align="center">
<tr>
                <td align="center" width="100%"><a href="$vboptions[forumhome].php$session[sessionurl_q]"><img src="$stylevar[titleimage]" border="0" alt="$vboptions[bbtitle]" /></a></td>
                <td align="$stylevar[right]" id="header_right_cell">
                                <if condition="$ad_location['ad_header_logo']">$ad_location 
[ad_header_logo]<else />&nbsp;</if>
                </td>
</tr>
</table>
<!-- /logo -->

<!-- content table -->
$spacer_open

$_phpinclude_output

$ad_location[ad_header_end]

<a href="http://s77.photobucket.com/albums/j77/bowhunterman/?action=view&amp;current=crazyarchery1.gif" target="_blank"><img src="http://i77.photobucket.com/albums/j77/bowhunterman/crazyarchery1.gif" border="0" alt="Photobucket"></a>
