Adding Banner To Header

[Gottcha]

This is my header template:

<!-- logo -->
<table border="0" cellpadding="0" cellspacing="0" width="100%" align="center" background="http://www.fragtraders.com/forums/images/misc/logo7_03.gif">
<tr>
<td align="left"><img src="http://www.fragtraders.com/forums/images/misc/logo7_02.gif"></td>
<td></td>
<td align="right"><img src="http://www.fragtraders.com/forums/images/misc/logo7_05.gif" width="158" height="150" alt="" border="0" align="right"></td>
</table>
<!-- /logo -->

<!-- content table -->
$spacer_open

$_phpinclude_output

How do i add banners to that header?
