Exporting images to jsPDF from html

I have a webpage on which I wish to print some HTML. To do so, I use html2canvas and jsPDF.

The issue that I encounter is that it does not print the images shown in the HTML.

My HTML and css looks as follows (complete code in fiddle):

.handsomeHtml {
 background: red;
}

.crazyFrog {
 background: url('http://e-cdn-images.deezer.com/images/artist/01eb92fc47bb8fb09adea9f763bb1c50/500x500.jpg');
 width: 500px;
 height: 500px;
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/html2canvas/0.4.1/html2canvas.js">
</script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jspdf/1.3.4/jspdf.debug.js">
</script>

<div id="someHtml" class="handsomeHtml">
  Hello, handsome HTML
 <br>
 <img class="crazyFrog"></img>
</div>

 <button id="savePDFbutton" onclick="savePDF()">
  save pdf
 </button>

Expected result:

Actual PDF result
