I've been seeing 2 distinct varieties of image spam recently.  

#1 contains image001.gif, a slew on innocuous words, and is 28Kb
to 29Kb long.  

#2 contains p.jpg and a bit of html, and is 26Kb long. 

#3 contains multiple images (each containing a line or so of the message)
and is approx 80Kb long.

FWIW, bogofilter has had no trouble with #2 and #3 and training is
helping with #1.
