And not all "decorative" images should be inserted via CSS. For example, if the image is a printer icon next to a "print" text, the code of the link could be:

<a href="..." title="Print this page">
<img src="ico-print.png" alt="" /> Print

This way, the icon will still be visinle with high contrast settings (css backgrounds disappear), and can also be resized if the user increases the text size.

In ant case, I also agree that many images *are* decorative because their only purpose is to enhance presentation,and not to convey any relevant information, even if they are not strictly "borders or lines".
