I'm looking for a cloud based photo storage solution. My wife and I want BOTH of our iPhones to sync to the same main library, which right now is on our Mac. I'm wondering what the best/easiest solution is out there. Can I truly configure iCloud Photos to meet my needs and the way that I want to use it (cost would be $2.99 a month for the 200 GB plan). I know the Apple plan works well with one library and one phone. Since I'm a Amazon Prime member, prime photos seems to meet everything that I'm asking for, and wondering if people have had any feedback with it. (cost $59.99 a year for unlimited video syncing). I'm also open to hearing other options that I haven't explored.....but I would prefer to stay away from Google.
