hello,
I have add printDownloadLinkAlbumZip() in album.php,and select User rights in downloadlist option,but it don't work,everyone can download album zip files,and I don't find anywhere to set uers's right,thank you.

You set user rights on the user accounts or via user groups.

it seems no seletion about downloadlist in user account or groups

No, as the option comment says the user needs "file(s)" rights.

ye,there is option of file right in galley tab of user's right ,but it don't work when I login in or visit with guest ,there need some php code to verify user right in album.php file ?

If you are logged in your are the admin so you have all rights. A guest should not be able to do anything. The download should then present a form.

Maybe you should open a ticket so we can investigate later.
