      <script type = "text/javascript">
         function FadeEffect(element){
            new Effect.Fade(element, { duration:1});
         }
			
         function ShowEffect(element){
            new Effect.Appear(element, {duration:1, from:1.0, to:1.0});
         }
      </script>
   </head>

   <body>
      <div onclick = "FadeEffect('hideshow')">
         Click me to fade out the image
      </div>
      <br />
		
      <div onclick = "ShowEffect('hideshow')">
         Click me to display the image once again
      </div>
      <br />
		
      <div id = "hideshow">
         <img src = "/images/scriptaculous.gif" alt = "script.aculo.us" />
      </div>
