Huh?  I am rather sure that the pixmap at least is created only at
(re)display time (if it is not yet in the image cache).  Not sure about
the X image.  Could be, however, that for image files, the load is
delayed to redisplay time as well (hard to do with XEmacs variants older
than 1 year or so as the file loader gets borked to non-binary when
dired has been loaded for some reason).  So that would mean that
technically you are right.

Poses an interesting problem when the file, indeed, is loaded
non-locally, since this will occupy tramp while in the redisplay loop,
and it better not try producing any terminal output.
