Ask HN: Best way to archive old pictures?

Hey HN, So I recently went back home and found my family's old pictures. Some of these date back to the late 19th century. As you can imagine, a lot of these images are not in the best of shape. I don't think they will survive the next two decades. I want to create a digital archive of these images that's accessible to all my family members. Essentially, I'm looking for: 1. Cloud based storage 2. Ability to create albums 3. Ability to tag people 4. Can make albums selectively available to some people 5. Can give 'admin' rights to some family members so they can add/remove pictures as needed. I'm willing to pay good money for a solution like this. Obviously, want something that won't shut down in six months. Any suggestions?
