We had a group of 12 of us that went on a cruise one time. We had a photo taken of all of us, which turned out fantastic. We decided to purchase only one and make copies. We went to a local Walgreens and they wouldn't make copies saying the picture was copyrighted. Nowhere on the picture did it say that but they insisted (we honestly didn't know anything about this).
We went to a local Kinkos, which turned out to be cheaper, and all 6 couples are the proud owners of a fantastic picture and great cruise memories.
Now this was 10+ years ago so who knows what the norm is now?
