title: How to send images through Worklight server without base64 encoding?
body: <p>I`m trying to find out how to send images to my back-end server using Worklight adapters.
  I know that I can send them through Worklight adapters using Base64 encoding but this implies in around 30% more traffic between the servers and some undesired processing overhead.</p>
  
  <p>For now I`m using the Phonegap FileTransfer library as I show below, but this creates a directly connection between the client and the back-end server not going through Worklight server as I want.</p>
  
  <pre><code>var options = new FileUploadOptions();
  options.fileKey="file";
  options.fileName=imageURI.substr(imageURI.lastIndexOf('/')+1);
  options.mimeType="image/jpeg";
  
  var headers = {"Content-Type": "image/jpeg"};
  options.headers = headers;
  
  var ft = new FileTransfer();
  ft.upload(imageURI, encodeURI(host + "/images"), imageUploadSuccess, imageUploadFail, options);
  
  function imageUploadSuccess(r) {
      WL.Logger.debug("Submit success! HTTP Status Code = " + r.responseCode);
      WL.Logger.debug("Response = " + r.response);
      WL.Logger.debug("Bytes sent = " + r.bytesSent);
      $.mobile.changePage('#SuccessPage');
  }
  function imageUploadFail(error) {
      WL.Logger.debug("submit error! source = " + error.source);
      WL.Logger.debug("target = " + error.target);
      $.mobile.changePage('#FailPage');
  }
  </code></pre>
  
  <p>Is there a way that I can do that?</p>
  
  <p>Thank you in advance.</p>
  
  <p>-- Edit --</p>
  
  <p>Another problem that occurs is that when my backend server receives the file, it seems corrupted and cannot be readed as an image.</p>
