How to make a field "Description" obligatory for filling?

In member.php find:
  if ($image_name == "")  {
    $error = 1;
    $field_error = preg_replace("/".$site_template->start."field_name".$site_template->end."/siU", str_replace(":", "", $lang['image_name']), $lang['field_required']);
    $msg .= (($msg != "") ? "<br />" : "").$field_error;
  }


Insert below:  if ($image_description == "")  {
    $error = 1;
    $field_error = preg_replace("/".$site_template->start."field_name".$site_template->end."/siU", str_replace(":", "", $lang['description']), $lang['field_required']);
    $msg .= (($msg != "") ? "<br />" : "").$field_error;
  }
