title: Save image with custom name
body: <p>I have the following image tag on a page:</p>
  
  <pre><code>&lt;img src="http://photo.com/img/p806792255-6.jpg" id="will6-1" alt="will6-1" title="will6-1" /&gt;
  </code></pre>
  
  <p>When a user does a 'Save Image As' the default name is <strong>p806792255-6.jpg</strong>.</p>
  
  <p>How do I make the default name appear as something else, like <strong>will6-1.jpg</strong>?</p>
