Oops I found it !
After the line :
<td bgcolor="$post[backcolor]" width="100%" valign="top">
I inserted this :
<table border="0" width="100%">
<tr>
<td width="79%">
<smallfont>$post[icon] <b>$post[title]
</td>
<td width="21%">
<smallfont>
<p align="right"><a href="showthread.php?postid=$post[postid]#post$post[postid]">Post #$countposts</a></td>
</tr>
</table>
Cool huh for a starter
