I think what they are getting at is a way to simplify declaring an image
file for universal use in all situations where an image may be used.
There are differnt situations where you may wish to use the same image
in different situations in the same scene but the different situations
require different declarations of the image file.

Consider -

#declare Image = image { png "my_image.png" }

height_field { Image ... }

normal { bump_map { Image } }

pigment { image_map { Image } }

function { pigment { image_map { Image } } }
