title: Problem with Fancybox. Iframe works only for the first link on the site
body: <p>I am testing Fancybox for Iframes and I noticed that on my Wordpress blog (and I guess everywhere else) the iframe is opened only for the first link on my home page.
  I have added the id attribute to all of the links though.</p>
  
  <p>Any ideas why is that and how to correct it?
  Below is the code. I only changed the name to popup and set to all links id="popup". On the examples page it also uses id, but on one link only.</p>
  
  <pre><code>&lt;script type="text/javascript"&gt;
      $(document).ready(function() {
          $("#popup").fancybox({
              'width'             : '75%',
              'height'            : '75%',
              'autoScale'         : false,
              'transitionIn'      : 'none',
              'transitionOut'     : 'none',
              'type'              : 'iframe'
          });
      });
  &lt;/script&gt;
  </code></pre>
