title: How to set different effects in nivo-slider
body: <p>I've got a nivo-slider on my site, but there aren't any effects except slidesUp, even though I have set the default installation.</p>
  
  <pre><code>         &lt;div class="slider-wrapper theme-default"&gt;
        &lt;div class="ribbon"&gt;&lt;/div&gt;
        &lt;div id="slider" class="nivoSlider"&gt;
  
    &lt;img src="/upload/banners/image1.png" border="0" alt=""/&gt;
    &lt;img src="/upload/banners/image2.png" border="0" alt=""/&gt;
    &lt;img src="/upload/banners/image3.png" border="0" alt=""/&gt;  
  
        &lt;/div&gt;
       &lt;/div&gt;
  &lt;script type="text/javascript"&gt;
  $(window).load(function() {
      $('#slider').nivoSlider();
  });
  &lt;/script&gt;   
  </code></pre>
  
  <p>and in header:</p>
  
  <pre><code>    &lt;script type="text/javascript" src="/scripts/jquery.js"&gt;&lt;/script&gt;
  &lt;script type="text/javascript" src="/scripts/jquery.nivo.slider.pack.js"&gt;&lt;/script&gt;  
  &lt;link rel="stylesheet" type="text/css" href="/css/nivo-slider.css"/&gt;
  </code></pre>
  
  <p>What should I do to make it works properly?</p>
