Bookmark Script & Image Map

[Casino Bills]

Anyone know how to add a bookmark script to a link inside a image map?

Im using this script: <a href="javascript:window.external.AddFavorite('http ://www.ilikepie.com', 'Welcome to www.ilikepie.com')">
<font face="Arial" size="2">Welcome to www.ilikepie.com</font></a>
