Don't want to share gallery by group, but by user

[NothingHere]

Hello all,

I want to set permission for each gallery individually by user ... I explain :
I have 3 gallery : gallery 1, gallery 2, gallery 3.
And 3 users : User A, User B, User C.

I want : G1 seen by A and B, not C.
2 seen by B only.
3 seen B & C.

Did I need to create a group for each users, and after select the album wich can be viewed ?

You have the idea.  At the simplest level, you can make a group for each album and then add the users to each group as desired.  There are no per-user permissions for albums or categories.
