Update "Who's Online" for VBA Gallery

[anarchystar]

Below this post is the codefor a mod that was already created by GrBear from vbadvanced.com. It will update users status in who's onlne to say they are in the gallery.
I want to know if this can be modified to work when the gallery is located at a subdomain. The original thread for this is located HERE and GrBear's code is below:

FIND:

else if (strpos($token, "/$modcpdir/") !== false)
	{
		if ($filename == '' OR $filename == 'index.php')
		{
			$userinfo['activity'] = 'modcplogin';
		}
		else
		{
			$userinfo['activity'] = 'modcp';
		}
		return $userinfo;
	}

After it add:

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