Hmm. I suppose that if the image can't stand on its own, then a story might help sell it. But if the image can't stand on its own, what good is it?
Put it another way, a family snapshot can have great emotional significance for close relatives even if the image is weak. All strangers can see in it , though is the image's weakness. Why should a stranger buy the snapshot, or, if given it, give it wall space?
Please don't tell me that I'm an ignorant barbarian, I already know that and admit it freely.
