multimedia-level property

Does css3 have a property for forcing alternative presentations.

One should be able to choose alternative presentations to be shown
instead of images in css.

A web page with big pictures might want to leave some of them out
when printing the page on paper.

I stumbled across this when I created the current default style
for my homepage at http://www.cs.helsinki.fi/u/twruottu/

The default style is trying to make the page look like an old vt320
video treminal, thus it should not show image(s), but it does because
css doesn't have a feature that could be used forcing them to be shown
as text.

The alternative style named "clowdy" should show the image(s), thus
it would be wrong to remove the image from xhtml-code. This is a style
thing, right?
