title: Fade In on image swap
body: <p>i´m using this script to swap image when click on a thumbnail:</p>
  
  <pre><code>$("#thumbs a").click( function() {
      var changeSrc = $(this).attr("href");
      $("#target").attr("src", changeSrc);
      return false;
  });
  </code></pre>
  
  <p>How can I make the changeSrc action to be like a smooth fadeOut and fadeIn of the other image?</p>
