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.

Unfortunately, much of the "image-only" spam that I have encountered does
not meet that criterion. Very often I encounter spam where the only image
is visible, but the text is hidden by matching the font with the background
and similar techniques. There usually isn't much text and what there is
would not run afoul the statistical filtering and is not suitable to be
picked out under phrases.
