title: Posting multiple images to tumblr using tumblr.js api
body: <p>I am trying to creating a app which can send posts to tumblr using tumblr.js api.
  I could send single image using the createPhotoPost method, but I have to send multiple image in a single post via this method.</p>
  
  <p>From the documentation it says that createPhotoPost method has a "data" parameter which can be an array with "URL-encoded binary contents"</p>
  
  <p>When ever I try to send something in the data Array it returns "[Error: form-data: Arrays are not supported.]".</p>
  
  <p>Can someone please help to solve this issue and please explain what should we pass in the array (Really I am not getting what is URL-encoded binary contents)?</p>
  
  <p>Thanks in advance</p>
