title: Reading local files with <input type="file">?
body: <p>I have seen some demos where mozilla guys dropped a photo into a dropbox and then edited it locally in the browser. But now i cannot find out the demo and i need to load images to my html, then edit them with canvas element, then upload them to server. I think there is a way of doing this but i cannot find any good explanation.
  Basically i need to take a picture on my clients computer and insert it into a canvas element without touching the server.
  Any help will be appreciated.</p>
