[4x4 Mecca]

jacquii, let me know if this works.

replace this

<!-- user info -->
<table cellpadding="0" cellspacing="$stylevar[cellpadding]" border="0" width="100%">
<tr>
<if condition="$show['avatar']">
<!-- check for staff -->
<if condition="in_array($post[usergroupid], array(5,6,7))">
<!-- I am staff so do this -->
<td class="alt2">

<table cellpadding="4" cellspacing="0" border="0" width="190" height="120" align="center" background="images/$post[username]_avatar.gif" nowrap="nowrap" no-repeat>
<tr>
<td width="46%">&nbsp;</td>
<td><img src="$post[avatarurl]" height="70" width="70" align="center"></td>
</tr>
</table>
</td>
<else />
<!-- I am not staff so do this -->
<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>
</if>

with this

<!-- user info -->
<table cellpadding="0" cellspacing="$stylevar[cellpadding]" border="0" width="100%">
<tr>
<if condition="in_array($post['usergroupid'], array(5,6,7,12,14)) AND $post[fieldXX]">
<div class="smallfont">
<object width="150" height="123.5"><param name="movie" value="http://www.youtube.com/v/$post[fieldXX]"></param><param name="wmode" value="transparent"></param><embed src="http://www.youtube.com/v/$post[fieldXX]" type="application/x-shockwave-flash" wmode="transparent" width="150" height="123.5"></embed></object>
</div>
<else />
<if condition="$show['avatar']">
<!-- check for staff -->
<if condition="in_array($post[usergroupid], array(5,6,7))">
<!-- I am staff so do this -->
<td class="alt2">

<table cellpadding="4" cellspacing="0" border="0" width="190" height="120" align="center" background="images/$post[username]_avatar.gif" nowrap="nowrap" no-repeat>
<tr>
<td width="46%">&nbsp;</td>
<td><img src="$post[avatarurl]" height="70" width="70" align="center"></td>
</tr>
</table>
</td>
<else />
<!-- I am not staff so do this -->
<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>
</if>
</if>

but edit the field number and user groups to match your site.
