My wife and I take a lot of pictures on our smartphones. What service can I pay for that will:<p>- Automatically upload our pictures from our smartphone<p>- Keep them private, viewable only to use, or family members.<p>- Nice gallery feature.<p>- Easy to export all data in one go.<p>I will pay cold hard cash for this. My wife will decapitate me if I lose our backup pictures of our kids when they were babies.
