Content providers that want to achieve this kind of layout:

  IMG1 text1
  IMG2 text2
  ...

which represents a list whose bullets are images, are usually left out
with two-column TABLE or even simpler sequence of P.

The issue is that the list semantics are lost.

The solution brought in by CSS come to doing:

<UL>
  <LI style="list-style: url(img1)"> text1
  <LI style="list-style: url(img2)"> text2
   ...
</UL>


Question: how do you associate ALT text for the url(img) ?

If the url(img) can be the id of an IMG element (rather than a pointer
to the image itself) there would be no problem, but I'm not sure
that's possible.

Note that support for this feature brings more than just ALT: WIDTH
and HEIGHT, IMG alignment (whether or not it's done in HTML or CSS),
usemap, events, etc, all of the IMG support in fact.

I just looked at CSS1 so I don't know if Frosting helps this issue.

Another question to ask is whether or not this issue (of pointing at
element rather than just data) is more generic than just for list
images.
