title: Laravel-dompdf (0.4) does not display remote images
body: <p>I use laravel Dompdf <em>(i.e. "barryvdh/laravel-dompdf": "0.4.</em>")* to generate pdf file. I reference image in HTML as:</p>
  
  <pre><code>&lt;img src="http://images.forbes.com/media/lists/companies/google_416x416.jpg" /&gt;
  </code></pre>
  
  <p>However when I generate PDF file, it tooks a while and gives me following error:
  <img src="https://i.stack.imgur.com/hVxLi.jpg" alt="enter image description here"></p>
  
  <p>I set  "<strong>DOMPDF_ENABLE_REMOTE</strong>" option to <strong>TRUE</strong>. However it did not make any change.</p>
  
  <p>Can you please help me.</p>
