Obviously we can't rely on cloud companies to keep to their original terms. Or for that matter, to stay in business at all. Remember Club Photo? They suddenly went down and never came back. Later they offered to sell its former customers CDs of their own photos. I remember that Steve Barr lost many thousands of photos, and even though he had been paying them hundreds per month for photo hosting, they still wanted several thousand dollars for CDS. He said forget it.
Fortunately all my photos are already on my hard drive. Only reason I even opened an account was for the 3rd party hosting.
