So you want both images to link to forumhome?
HTML Code:
<!-- logo -->
<a name="top"></a>
<center>
<table border="0" width="100%" cellpadding="0" cellspacing="0" align="center" style="background-image:url($stylevar[imgdir_misc]/headbg.gif)">
<tr>
<td align="left" valign="top"><a href="$vboptions[forumhome].php$session[sessionurl_q]"><img src="$stylevar[imgdir_misc]/head_left.gif" border="0" alt=""/></a></td>
<td align="right" valign="bottom"><a href="$vboptions[forumhome].php$session[sessionurl_q]"><img src="$stylevar[imgdir_misc]/head_right.jpg" alt="" /></a></td>
</tr>
</table>
</center>
<!-- /logo -->
