I disagree.  Yes, in many cases the IMG is the primary and the text is
a bandwith conserver, but in many cases, such as the one Stephanous
gives, that is not true at all.  Having the text as the primary and
the image hooked in from the stylesheet makes a lot of sense for logos,
pull quotes, decorated headlines, and so on.  It makes life better
for indexing agents, text browsers, the 20% of the browsers that run with image
loading disabled, the mail-out of pages to HTML-impaired mail agents.

I think Stephanous' idea is a good one.
