Except that, contrary to bgcolor, the height and width attributes can  
help solve a real problem: page jiggling while the images loads. It's  
somewhat like the type="image/jpg" attribute you can set for links:  
it gives advance information on what the external content is supposed  
to be.

In this case, height and width are inherent properties of the  
document if we consider the linked image as part of the document,  
much alike the type="" attribute on a link. Sure, we could use  
style="width: 32; height: 32" instead of width="32" height="32", but  
most of the time the size of an image isn't a matter of style, it's a  
matter of what the image is.
