hi encasa.

A solution is like this:

- Clone myAlbum-P as myalbum0/, myalbum1/ etc.
- Make a directory in uploads/ whose name is unexpected from others. (777)
- Set the directory's name into preferences of cloned myAlbum-P.
- Set to deny accessing the cloned modules from others in groups admin.

Of course, once the name of the directory is known by others, all photos are downloaded by him.
But, nobody knows the name, if you set Options -Indexes.
