Yes, but I think that doesn't suffice.  The problem with bookmarks is
that the display window function is run after the bookmark handler, so
we have no clue in which window the bookmarked page is going to be
shown.  It may be the current window, an existing other window (which
might already show another page of the doc and thus already has an entry
in `image-mode-winprops-alist'), or a completely new window.

Bye,
