Not likely.  For a variety of reasons, the (:if:) markup is processed
long before the Attach: markup is ever processed.  The real way
to achieve this is probably to have max-width and max-height
wikistyles and let PmWiki try to figure it out from there.

    %max-width=200px max-height=200px% Attach:image.jpg

But of course it's worth noting that this would still only work
for attached images.
