You mean the number one source of browser bugs (or perhaps the "coding 
errors" you referred to were browser programmers').

It also means that ALT text for small images is unreadable in nearly all 
existing browsers.  For this reason, many people recommend against using 
WIDTH and HEIGHT attributes for small images with important ALT text.

A nice perfect-world solution, IMO, would be to give the width and height 
in an external style sheet, which means that an image's width and height 
need only be specified once for an entire site.  Of course, it's not a 
perfect world, so this solution is garbage.
