The cover is related to the story, but I believe this cover was also used for a three book anthology which included other stories in addition to "Say Cheese and Die". The main character acquires a camera that either predicts the future or causes bad things to happen... he takes this picture of his family at a BBQ and then die in a car accident or something.
