Ease access to image result for given query by image_search

- Copy images to accessible directory
- Return URL paths to them to ease access
- This is to be used in the web interface to render image results
  directly in browser
- Return image, metadata scores for each image in response as well
  This should help get a better sense of image scores along both
  XMP metadata and whole image axis
