Amazon Family Vault now provides an unlimited storage for up to five people
Amazon updated its Prime Photos service with a new feature called “Family Vault” where Prime subscribers can invite their families or friends to access their own catalogue of pictures as well as videos. Those media types can be uploaded to the cloud by anyone who has approved for an access. Then, those medias can be found via Prime’s search feature which, by the way, is another thing that is being updated.
In the past, the Prime users were limited to send only the links of the photos, but now, they can open their library to the people they know. Additionally, your family, your friends or anyone to whom you give an access have a privilege to upload unlimited photos and up to 5GB of videos. You, on the other hand, as the owner of the library can order those media types directly from the Amazon, and even print them.
However, the Family Vault requires at least one person to be an Amazon Prime member.
