title: jQuery validation - required working but accept not
body: <p>im uploading an image and trying to validate it before with jquery. Here is my code:</p>
  
  <pre><code>&lt;script type="text/javascript" src="http://jzaefferer.github.com/jquery-validation/jquery.validate.js"&gt;&lt;/script&gt;
  
  &lt;script type='text/javascript'&gt;
  $(document).ready(function(){
      $("#form").validate({
          errorLabelContainer: "#message_box", wrapper: "li",
  
          rules: {
              image: {required: true, accept: "jpg|jpeg|png|gif"}
          },
          messages: {
              image: {required: 'Required!', accept: 'Not an image!'}
          }
      })
  });
  &lt;/script&gt;
  </code></pre>
  
  <p>Required is working - if i insert no image i get an error. But accept isn't working (anything i insert passes) and i cant figure out why. Any ideas? :)</p>
