title: Different images for IKImageBrowserView and Quick Look
body: <p>I'm writing a program that shows images from internet.
  I'm using a IKImageBrowserView for it, using NSURLs.
  I'd like to show thumbnails in IKImageBrowserView and full res images in Quick Look.
  Quick Look is automatically invoked by IKImageBrowserView.
  Can i in some way tell to Quick Look to show a different NSURL from which is showed in IKImageBrowserView?</p>
