Yes but, most of the image-only spam we have encountered contains a
non-clickable link to the target, encoded into the image itself.  As
much as I dig Declude and URIBL, they don't perform OCR(yet...).

URI filtering is very effective at stopping these kinds of spams
(assuming 
the domain is listed).  SURBL/URIBL tend to grab on to these fairly
quickly. 
URI blacklists are designed to catch this kind of stuff since it focuses
on 
the spamvertised link / image.
