title: Apply a red border to all images hosted on CDN with jQuery
body: <p>I am using Amazon S3 and certain images are hosted there. Its kind of a pain to check each image in turn to verify its coming from the CDN and sometimes new images are added and someone forgets to upload them, and I thought it would be nice to have a visual cue - accessible from a debug panel.</p>
  
  <p>I'd like to draw a red border on all images on my page that are coming from the CDN.</p>
  
  <p>How could I do this with jQuery. The images would need to be identified by a URL (eg. 'images.example.com').</p>
  
  <p>Extra points if you have a cleverer solution than a simple red border.</p>
