Well, of course, this is what happened before "in-line" display came
in with Mosaic.  I always quite liked having an external viewer
start-up to view images, but I suspect it wouldn't satisfy most
people (especially people who are obsessed with appearance rather
than content).  The idea of being able to configure a browser to
either display images in-line or pass them to a helper app is
interesting, but I don't think it would work in practice - too many
web pages now are tightly-bound mixtures of text+graphics (e.g., 
newspaper/magazine sites).
