You appeared to suggest that it was no longer necessary to have images
with alt="" as you could suppress them with CSS (there was a lot of
guessing, there, as what you wrote really wasn't clear).

In practice, assistive technology behaves as though it were the visual
browser (normally IE) that it is based upon, so suppressing images with
CSS will suppress them for people using the out of the box browser as
well.  That's partly because AT has to work with real world web sites,
and in the real world, hardly anyone cares about accessibility, and
even fewer use @media in the style sheet, especially for anything other
then visual or print media.

Looking at another article in the thread, you may have been thinking
about spacer images, but images are also used for decoration.
