                  That&#39;s the basic logic for a preload routine. You may
                  have noticed on the readystate == 3 branch that we are
                  calling a function named setOpacity(). We do this to ensure
                  that the image opacity is set to 0 before it is rendered by
                  the browser after the readyState == 4 branch has been parsed.
                  The function it hooks into enables us to set opacity for the
                  browsers that support it. Opera will simply just display the
                  images without using opacity. The setOpacity() function looks
                  like this:
               </p>
               <p class="code">
                  function setOpacity(opacity, id)<br />
                  {<br />
                  var el = document.getElementById(id).style;<br />
                  el.opacity = (opacity / 100);<br />
                  el.MozOpacity = (opacity / 100);<br />
                  el.KhtmlOpacity = (opacity / 100);<br />
                  el.filter = &quot;alpha(opacity=&quot; + opacity +
                  &quot;)&quot;;<br />
                  }
               </p>
