  That's curious. I went to check and noticed that when you zoom out on the 
openseadragon thing, the OCR button uses the lower resolution image. I don't 
think this is expected.
  
  Compare:

  Fortunately, if you put in an arbitrarily large image size (I guess something 
like 3000px is enough for most cases), the thumbnail server gets you the higher 
resolution avalaible, and OCR quality increases.
