When many people have access to a single catalog, it can be beneficial to create galleries to which individual users have access.
When you create a gallery, you can choose to make it public or private. You can choose to make a public gallery Read-Only so that other catalog members can view but not change your gallery.
To change the privacy settings of a gallery:
In the Organizers panel, double-click the name of the gallery.
Select privacy settings for the gallery:
Public galleries are available to all members of the catalog.
Private galleries are only available to you.
The Read-Only option restricts the ability for other users to change your public gallery. You are still able to modify the contents of the gallery.
Click Save.
