As Magritte so poignantly expresses, a picture of a pipe is not a pipe. But as Plato mused, is a pipe even a pipe? What is a real pipe? Surely not that thing you hold in your hand, that did not exist before it was made, and will one day again be dust. The only real pipe is the Form, the idea of the pipe. It is not of the physical world, only of the intellectual, and is eternal and unchanging.
