The wizard that puts the images all single files is in trouble anyways.
I don't think he has a choice in the matter - my impression is that they distribute themselves fairly randomly, according to some law of Brownian Motion. It's possible for them to end up strung out in a line, but far more likely they'll cluster.
As DM, I'd rule that if the chain was broken, the remaining images would automatically redistribute themselves enough to cover the gap.
