Not working for Albums with password

[switschel]

This plugin works fine when photos are set public/private. It will not work proper when albums are password protected. For example a password protected public album will check for password but the photos are accessible directly without logging in nor entering the correct password:

Check if public (as is)

if ($isAdmin=== true||$photo->public==='1') {
    # Photo public
    return $photo;
} else {
    # Check if album public
    $album  = new Album($database, null, null, $photo->album);
    $agP    = $album->getPublic();
    if ($agP===true) return $photo;
}

It tried to solve it by my own but I'm not sure how to pass the entered password to this getPhoto.php.

Check if public (with password check)

    if ($isAdmin === true || $photo->public == 1 ) {
            # Photo public
            return $photo;
    } else {
            # Check if album public
            $album  = new Album($photo->album);
            $agP    = $album->getPublic();
            #Where to get the password? $_GET['password'] isn't working.
            $acP    = $album->checkPassword($password);
            if ($agP===true&&$acP===true) return $photo;
    }
