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
</a>

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".

Regards,
Ramón.
