title: How can i "getImageData" from another website? SECURITY_ERR: DOM Exception 18
body: <p>I'm working on an online app to manipulate images.
  It works fine when doing it with local files (on the server) but as soon a I try it with another source it breaks.
  The reason for this seems to be a security limitation, qoute from <a href="http://www.whatwg.org/specs/web-apps/current-work/multipage/the-canvas-element.html#security-with-canvas-elements" rel="nofollow">whatwg</a>:</p>
  
  <blockquote>
    <p>Whenever the getImageData() method of the 2D context of a canvas element whose origin-clean flag is set to false is called with otherwise correct arguments, the method must raise a SECURITY_ERR exception.</p>
  </blockquote>
  
  <p>So I wonder can I get around this somehow?
  The images will all come from a google API, and I really want to skip saving the images if i can.</p>
  
  <p>Thanks.</p>
