You could do the following as a quick and dirty solution:

open your includes/functions_newpost.php.

Find:

PHP Code:

    // check max images
    require_once('./includes/functions_misc.php');
    require_once('./includes/functions_bbcodeparse.php');
    if ($vboptions['maximages'] != 0 AND fetch_character_count(parse_bbcode($post['message'], $foruminfo['forumid'], $post['enablesmilies'], 1), '<img') > $vboptions['maximages'])
    {
        eval('$errors[] = "' . fetch_phrase('toomanyimages', PHRASETYPEID_ERROR) . '";');
    } 


Add below:

PHP Code:

    if ($bbuserinfo['usergroupid'] != 6 AND fetch_character_count(parse_bbcode($post['message'], $foruminfo['forumid'], $post['enablesmilies'], 1), '<img') > 0)
    {
        eval('$errors[] = "' . fetch_phrase('toomanyimages', PHRASETYPEID_ERROR) . '";');
    } 


This will give a "Too many images" error for all users that are not in the Admin group (groupid=6)
