You need to edit postbit/postbid_legacy and memberinfo. Look for this code:

PHP Code:

            <if condition="$show['avatar']">
                <div class="smallfont">
                    &nbsp;<br /><a href="member.php?$session[sessionurl]u=$post[userid]"><img src="$avatarurl" alt="<phrase 1="$post[username]">$vbphrase[xs_avatar]</phrase>" border="0" /></a>
                </div>
            </if> 


Then I would just add a second conditional like this:

PHP Code:

            <if condition="$show['avatar']">
<if condition="bbuserinfo['usergroupid']==8>

DO SOMETHING HERE

<else />
                <div class="smallfont">
                    &nbsp;<br /><a href="member.php?$session[sessionurl]u=$post[userid]"><img src="$avatarurl" alt="<phrase 1="$post[username]">$vbphrase[xs_avatar]</phrase>" border="0" /></a>
                </div>
</if>
            </if>
