Also, for reference, here's the corresponding code from the postbit template:
Code:
<if condition="$show['avatar']"><td class="alt2"><a href="member.php?$session[sessionurl]u=$post[userid]"><img src="$post[avatarurl]" $post[avwidth] $post[avheight] alt="<phrase 1="$post[username]">$vbphrase[xs_avatar]</phrase>" border="0" /></a></td></if>
again of course $post would correspond to $userinfo if that's the variable you used in the above code.
