first of all thanks for the great job.

I installed zenphoto version 1.2. I would like to know if there is a way to create an user with special grants for (sub)*-albums (not only album).

My goal is to create an user that can only see selected albums and or subalbums.

Sorry, no, rights can be set only for top level albums.

that's sad. Is it possible to set rights for dynamic albums. By doing so, do I can use it, as a workaround, to create specific views of albums with specific users?

So long as the album is gallery level you can set rights for it
