Control Panel » Display Options » Default Header

This is what I have for mine; adjust the HTML accordingly to your needs:

HTML
<BR />
<TABLE align="center" width="800">
<TR>
<TD align="center" valign="middle" width="325">
<a href="http://LINK TO YOUR FORUM/" target="_top">
<IMG width="300" height="50" src="LINK TO IMAGE" border="0" alt="NAME OF YOUR IMAGE" align="left"></a>
</TD>
<TD align="center" valign="middle">
<!--// I have my banner ads here //-->
</TD></TR></TABLE>
