Installed a banner ad. How to space away from header image?

[fridaypassion]

Hi

I've just installed an ad banner hack but the banner appears right next to my header image (both centred)

How would I change the code to put in some spacing below my title image.

This is my header code at the moment

cellspacing="0" align="center">
<tr>
<td align="center"><a href="$vboptions[forumhome].php$session[sessionurl_q]"><img src="$stylevar[titleimage]" border="0" alt="$vboptions[bbtitle]" /></a></td>
<td align="center">
&nbsp;

</td>
</tr>

</table>

<tr><center>$banner</center></tr>

<!-- /logo -->

<!-- content table -->
$spacer_open

$_phpinclude_output
