Help me apply different style to signatures

[Kevlar]

I want to do something like this... Here is the original code...

<if condition="$post['signature']">
  <!-- sig -->
   <div class="signature">
	__________________<br />
	$post[signature]
   </div>
  <!-- / sig -->
  </if>

and I want to do something like this

<if condition="$post['signature']">
 <!-- sig -->

<if condition="$usersusergroup = admin OR $usersusergroup = supportingvendor">
<div class="fullsignature">
	__________________<br />
	$post[signature]
   </div>
<else>   
<div class="minisignature">
	__________________<br />
	$post[signature]
   </div>
</if>
  <!-- / sig -->
</if>

Basically, I've set it up so I chop users signatures at 200 pixels tall. However, I would like it so that admins and supporting vendors would not be chopped at 200pixels. I already have the style sheets setup... just have to figure out how to do the IF statements.

Find this
<if condition="$usersusergroup = admin OR $usersusergroup = supportingvendor">
change to
<if condition="($post[usergroupid] == X) OR ($post[usergroupid] == Y)">

By Default the Admin usergroup is 6 so change X to 6, and then find the id number that supportingvendor is. and replace it for Y
