Make these customizations:
  • To change the Loud speaker image change
http://4.bp.blogspot.com/-7ZFQXCvcnjQ/TlfjPMxiBJI/AAAAAAAAEzM/jrV-qvI_xqM/s400/updates1.gif
  • If you wish to increase the scroller width size then edit this width: 430px;
  • Replace 0080ff with your link colour.
  • Replace HEADLINE TEXT with anything you wish to write as announcement or updates. Write any text description you want.
  • Replace # with headline page link/url. On clicking this link the visitors will be taken to the headline related page. If you don't want to link your Headlines then simply delete # next to each HEADLINE TEXT  that you don't wish to hyperlink.
  • To change the scroll change delay time kindly edit 1000 . The more your decrease this value the faster will the links scroll up and down.
           4.  Finally save your widget and you are all set!
