Answer 1

You can do this in plain CSS by removing the img from the a , and adding the following:

<style type="text/css">
    #download 
    {
      background-image:url(download.png);
      display:block;
      /* todo : put height and width of image here */
      width:100px; 
      height:100px;
    }

    #download :visited
    {
      background-image:url(download_visited.png);
    }
</style>
