title: Use data from img tag
body: <p>I have an image tag that looks like:</p>
  
  <pre><code>&lt;img data-original="imgserv/profilepics/2/702296.jpg" src="imgserv/blank.JPG" 
   id="702296" user_ip="65.346.36.192" class="lazy"&gt;
  </code></pre>
  
  <p>In jQuery, if I do </p>
  
  <pre><code>$('.lazy').on('click', function() {
    alert(this.id);
  });
  </code></pre>
  
  <p>I'll get the specific <code>id</code> I need.</p>
  
  <p>How can I make it so that I can also retrieve the data inside <code>user_ip</code>?</p>
