I don't know about Thunderbird, but with a Bayesian system
you teach it what is spam and what is not.  That means that if you don't
normally receive image-based messages you can teach it to classify them
as spam.  I have never had my Bayesian system (Bogofilter) mis-classify
a message because it contained an image.  The messages it has
difficulty with are those spam messages that are very similar to the
*normal* non-spam messages you receive. Though after some period of
training it is even very good at dealing with these, in my experience.
YMMV, though, because some people's view of legitimate email can be
quite different from that of others.
