title: jQuery plugins external functions
body: <p>I am building my first jQuery plugin, a slideshow. It's working fine, I can pass as parameters, the direction, the interval and speed at which the images move.<br>
  Now I want to add a start and a stop function, to create or destroy the </p>
  
  <pre><code>obj = window.setInterval()
  </code></pre>
  
  <p>I use to change the images, so I can access those functions outside like:</p>
  
  <pre><code>slideshow = $('#slideshowstrip').slideshow();
  slideshow.start();
  slideshow.stop();
  </code></pre>
