title: Dropzone file upload use unique name
body: <p>I am using <a href="http://www.dropzonejs.com/" rel="nofollow">dropzone</a> for file upload. I just love it. But one thing I want that, I want to use the unique name for each file. So that there will be no repeat file names in the dropzone. So any help and suggestions will be really appreciable. Thanks.
  Any one there for help?</p>
