HTML Code:
<table width="100%" class="tborder" border="0" align="center">
<tr>
<td class="alt1"><table width="100%" border="0" cellspacing="5">
<tr>
<td valign="middle"><div align="center"><strong><a href="$foruminfo[sponsorlink]">$foruminfo[sponsorname]</a></strong><br />
<a href="$foruminfo[sponsorlink]"><img src="$foruminfo[sponsorimage]" alt="$foruminfo[sponsorname] Image" border="0" /></a></div> <div align="center">$foruminfo[sponsordescription]</div></td>
</tr>
</table>
This fixed my centering issue
