HTML doesn't define an %align=center% for images (and browsers would
have difficulty getting text to "flow" around a center-aligned image).
But %center% works for centering an image if you aren't interested
in flowing text around it.

Two potential problems:  (1)  As written above the margins are no
longer "defaults" but mandatory settings -- there's no simple way
for an author to change or eliminate the images' margin settings,
and (2) it's too general, it puts margins on images (especially
non-floating) where they aren't wanted.  So, if a site is using
wikismileys, or images to visually tag links to external sites,
then those images get margins added to them as well.

I suspect the answer is going to be that we predefine %imageleft%
and %imageright% wikistyles that provide appropriate margins
and get authors to use those.
