I like the idea.

But I have some question about the "em-sized-images" in general: I can
imagine that the calculation the browser does is always a "compromise"
and never "pixel-exact". After all the browser will need to define how
many pixels wide the picture will be to display on screen. We usually
get pictures from agencies which are already scaled to the correct
(px-)size. How can I make sure the browser doesn't make any unnecessary
"resizes" if I give its size in "em"? Or imagine a logo, some icon or
other stuff. Won't it look "ugly" if incorrectly scaled by the browser?
Assume only "normal sized".

Cheers,
