Hi Richard,
There are a couple out there... I created one for
myself (V1."un") that does something similar... It
relies on a couple of support files for mime-types and
icons. Here's the code... if you like the idea, I can
zip up the icons and extension-to-mime folders and
send it to ya. My website (www.jwfarrell.com) is
supposed to be online later this afternoon (after a
week of promises from my ISP), so you'll be able to
look at the code in action.
