Imagine a life size statue, part of a crucifix in a cathedral, falling to the floor as stress bearing shoulders break apart. Imagine workmen carefully wrapping the statue in a linen altar cloth. They place the arms over the torso so they fit under the cloth. Imagine workers cleaning the statue with a cleaning fluid. Imagine a chemical reaction taking place that forms an image on the cloth. Imagine a priest thinking this was a miracle. Imagine a cash strapped bishop changing the story a bit and adding some blood from the cathedral hospital.
I think a partial hat tip to Colin is in order.
No that is not the shroud image. That is John Lennon, the first thing that came to mind with all those imagines.
