I presume you mean that they don't look good in the <style> case, but 
actually, I don't know if that's accurate. Don't forget that in many cases 
the page will have multiple such images. You have to duplicated the img-* 
markup in each case. You only have to give the <style> block once.

That's a valid concern, I think.

FWIW, my original thought in this direction (which I unsuccessfully tried 
to peddle in #whatwg) was to use a dedicated language rather than 
something backwards-compatible with CSS.

The main idea of Adam's idea is it doesn't have to be, no?
