about album protection

Hello,
I have problem in control access in album.
I have a album want to set the permission.

The permission is that everyuser can view the hightline of album(without logging in). But cannot enter it. If users try to enter, he/she will be prompted to login, and then they can enter the album.

It seems that the above cannot be set in permission section. At least I want access control but let all people(without logging in ) can also view the highline of album(not hide the album, but don't allow then enter).

How can I do so?
