Snapfish has been around for a long time--I first wrote about this photo sharing site back around 2001. It is completely free, with unlimited photo storage. That said, the site's photo sharing service exists mainly to support an online printing business, so Snapfish maintains your photo collection only on the condition that you occasionally purchase something. Don't make any prints, photo books, or photo gifts at least once a year, and your photos might be disappeared. A lot of folks store their photos on Snapfish, but it seems to me that this really only makes sense if you use Snapfish's printing services frequently. (Like Shutterfly, Zazzle, and other sites, Snapfish offers a broad collection of customized products, from prints to clothing to photo gifts). Snapfish also has some unique sharing tools, like private "rooms" where you can chat and share photos with select friends and family.
