title: Replace SRC attribute with data-original
body: <p>I have installed LazyLoad in my WordPress theme. I'd like to change all SRC attributes of images that use lazyload to data-original.</p>
  
  <p>This:</p>
  
  <pre><code>&lt;img class="lazy" src="something.png"&gt;
  </code></pre>
  
  <p>To this:</p>
  
  <pre><code>&lt;img class="lazy" data-original="something.png"&gt;
  </code></pre>
  
  <p>I have tried many things. Right now, this is what I have:</p>
  
  <pre><code>$( 'img.lazy[src]' ).attr('src').replaceWith( 'data-original' );
  </code></pre>
  
  <p>How do I replace the SRC attribute to data-original?</p>
