title: Is it possible to fetch part of a remote image in javascript?
body: <p>I want to extract EXIF data from remote images using Javascript. It works OK at the moment but it gets quite slow when the image is large since I download the entire image before extracting the EXIF data.</p>
  
  <p>EXIF data is always within the first 128kb of an image (I believe) so I really don't need the entire image.</p>
  
  <p>Is it possible to somehow only fetch the first XXX kb of a remote file with JS?</p>
