Me too.  Subject says "pictures of baby" or whatever, and then follow 
images with no body text.  Definitely not spam.  There's nothing wrong 
with the current Bogofilter functionality in this regard.  The subject 
and other header info is enough to match ham and spam for me, especially 
because emails from friends and family have hammy tokens, but also 
because I add in the ASN tokens, etc., to help add spamminess to the 
others.  These so-called image spams do not currently affect me.

However, that being said, I think that the idea of matching certain 
tokens inside of jpegs could be worth looking into.  Calling emails with 
an image and less than 5 lines of text a spam is not.  Too procedural, 
not statistical.
