well, i'd say above this
PHP Code:
// do posts from ignored users
if (($ignore[$post[userid]] and $post[userid] != 0)) {
eval("\$retval = \"".gettemplate("postbit_ignore")."\";");
} else {
eval("\$retval = \"".gettemplate("postbit")."\";");
}
return $retval;
then if you just put them in specific usergroup "contributers" or whatever then you could just do a if($bbuserinfo[usergroupid] == #) {$image = '<img src="blank.gif">';} else {$image = ''}; then put $image wherever you wanted in the postbit
