Only post in own galleries

[Juan Carlos]

I'm new to this and I'm trying to do something but I can not.
How can I make users just put photos in their own galleries.
The admin creates a category and users can only put photos in the categories that they create within it.
Example:
I (admin) created a category called "TRIPS", then the user (user_1) creates their albums within "TRIPS" as
- My Trip 1
- My Trip 2
User_1 can only upload photos to these albums (My Trip 1 and My Trip 2) and can not upload photos to any other place outside of them.
Sorry if this is a stupid question but I can not find the solution

Two ways if they have a personal gallery permission they can create their own mini gallery.

If you have main categories. You can deny other member groups having permissions to add to a gallery by using the category permissions link on each category to deny a group.

Thank you but how can see the user galleries inside main categories that I create.

Example
Gallerie
  - TRIPS (created by admin)
      - My Trip 1 (created by User_1)
      - My Trip 2 (created by User_1)
      - My Trip 1 (created by User_2)

  - WEEKENDS (created by admin)
      - My weekend (created by User_3)

 If a users clic in "TRIPS" they see the 3 albums inside that Gallery

I don't have an option to create user galleries inside admin gallerys. User galleries are separate in their own personal gallery
The only way you can do that is if you create a new membergroup for that user. Then give permission to only that category under the admin category to that user's membergroup.
