title: Using a fontawesome icon as alt-text for an <img>
body: <p>I have some images that are loaded with a cheap trick after the DOM is ready:</p>
  
  <pre><code>&lt;img src="" data-src="/path/to/img" alt=""&gt;
  </code></pre>
  
  <p>I'm just putting the content of <code>data-src</code> into the <code>src</code>-attribute with JS. Nothing fancy.<br>
  But as there are a some hundred images to load this takes some time. So I was trying to use the unicode of a FontAwesome icon as alt-text to display a cogwheel as placeholder:</p>
  
  <pre><code>&lt;img src="" data-src="/path/to/img" alt="&amp;#xf013;"&gt;
  </code></pre>
  
  <p>Unfortunately this won't work because the whole FontAwesome-magic isn't clicking.<br>
  Has anyone ever tried the same? Is this possible after all?</p>
