title: upload picture to server from clipboard
body: <p>I was looking a long time for the solution, but I can not find any. Is there any possibility to upload picture from clipboard to file on server (by pressing ctrl+v) ?
  It could work for Chrome.</p>
  
  <p>Use PHP, Javascript, jquery, or maybe sth else? Some external extension for chrome?</p>
  
  <p>Thanks a lot.</p>
