As a Premium member, you can decide when creating a new album whether to share it privately or publicly.
If you want to set an album that you have already created to private, you need to select the relevant album in photo manager and click on “Edit album”. You can now change the album from public to private. You can either share the album with selected members or with all your friends. The advantage of the latter is that new friends that you add will automatically be given access to your photo albums.
Clicking on "Manage access rights" enables you to give selected contacts access to your album at any time. You can select individual members from your contacts list, copy the access list for existing albums or add individual users manually.
You can edit your photos and albums here.
