Here's what I did...

1) Download a high-resolution image of the icon you want to use.
2) Then (if Using Leopard go to next step) open the Icon with GraphicConverter & save it.
3) In Finder, select the saved File (with a preview icon that shows the image) and hit APPLE-I (or select File -'Get Info')
4) In Finder, select the file you want to have that Icon, and hit APPLE-I (or select File -'Get Info')
5) Drag the top left image of the icon you want onto the top left image of the fiel you want it on.
6) Delight the world with your new-fu!

After selecting "Application" for the File Format I also unchecked the

Anyone know how to get an icon like the one
in /opt/local/share/icons/hicolor/24x24/apps/gimp.png to be the
Application Icon that can be placed on the Dock?
