title: load image asynchronous
body: <p>If I have an image tag like the following:</p>
  
  <pre><code>&lt;img src="myimage.jpg" /&gt;
  </code></pre>
  
  <p>and if I add "async" to it:</p>
  
  <pre><code>&lt;img async src="myimage.jpg" /&gt;
  </code></pre>
  
  <p>will the image load asynchronous?</p>
