title: createObjectURL unsupported in Opera
body: <p>Checking this adress: <a href="http://caniuse.com/#feat=bloburls" rel="nofollow">http://caniuse.com/#feat=bloburls</a> you can see this is the only desktop browser with no support for this feature. 
  How can I find a workaround for this without to much change in my code?</p>
  
  <pre><code>var jpeg = NewBlob(imgData.array.buffer, "image/jpeg");
   var url = DOMURL.createObjectURL(jpeg);
  </code></pre>
