In the example screenshot below, you will notice that we've added both a text link and a graphical icon link to the toolbar. The text link goes to the Google search engine and the telephone icon goes to a phone list. We can mix and match text and images and add as many extra links to the navigation bar as our user's browsers will comfortably allow. Using this method, all our custom links will appear after the dynamic navigation links that are generated natively by Sharepoint Portal Server 2003. If you have links that you want to always be available to every portal user all the time, this is an easy way to add them.
To add links like this to your portal, add the code below to your OWS.JS file and customize it as needed.
I was inspired to write this script while learning techniques presented in our Extreme Makeover - Portal Edition class, which is being offered again the first week of December, 2006 in Chicago.
