As an added benefit to its Prime Photos service, Amazon offers Prime members Family Vault Photo Storage for free. It allows you to share your photo storage with up to five people and view and collect everyone's photos in the Family Vault, where they will stay private until you choose to add them. Prime Photos organizes your photos automatically, with no tagging required, and allows you to find photos by searching for things, people, or places in your images. Additionally, you can order custom photo products directly from your Prime Photos account and get free Prime delivery. Both Prime Photos and its Family Vault are accessible via the web or via free apps for iOS and Android.

Note: This service is available for Prime members signed up for either the monthly or annual Prime plans. (This does not include Prime Video members.)
