Ion performs better than picasso, so I'm using that instead.

Get rid of 'Rest of stats' generic OCR section
Get rid of commented out Ion resize image, url manipulation

* Get rid of the commented out resizing of screenshots to the image
  view - resizing isn't needed as screenshots fall within ImageView
  sizes.
* Remove altering of image URI.  This was added when it wasn't clear
  why the image wasn't being received properly (turned out to be
  image size problem, dealing with large photos instead of screenshots
  displayed in ImageViews)
