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...).

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.
