i have a problem to edit includes/function_online.php to integrate coppermine in it.
My forum path is /
my gallery path is /gallery/
so i edit function online, i add:

  		case 'gallery':
  			$userinfo['action'] = $vbphrase['viewing_gallery'];
 			$userinfo['where'] = "<a href=\"$userinfo[location]\">$userinfo[location]</a>";
  			break;

between other case
and after

  		else
  		{
  			$userinfo['activity'] = 'modcp';
  		}
  		return $userinfo;
  	}

i add:

  	else if (strpos($token, "/gallery/") !== false)
  	{
  		{
  			$userinfo['activity'] = 'gallery';
  		}
  		return $userinfo;
  	}

but it doesn't work
someone can help me?
