Discussion following DiscardImage -> DiscardPage
Rational:
It walks like a MobilePage or FixedPage. It does not quack like an Image
. In fact, it contains an Image, so it cannot be duck, at most its a box (with a duck in it): hence its a Page.
Clear as mud.
update That is all done, but there is discussion below that may not be resolved yet.
