Image w/ description tooltip- By Dynamic Web Coding (www.dyn-web.com)
Copyright 2002 by Sharon Paine
Visit http://www.dynamicdrive.com for this script

03/10/06 - SDW - Modified to allow use from within InnovaStudio content editor
  This file needs to be included in the page used to display the content
  and the doTooltip function has been modified to accept the data that was being
  stored in the array. The 2nd parameter can now be 'none' or '' if no image is 
  to be displayed. The path to the images is set to Content/Images.

put tooltip div just before </BODY>. */
