I would like to view full cover of pdf ebook originally purchased on Kindle Store and then converted with Ultimate. I see the thumbnail on my adobe reader app on my ios device. I would like to know how to extract the cover image as I would like to read the editorial details on the expanded cover. The full cover image is not viewable in the Kindle App (even on original file), Adobe Acrobat, or Foxit PDF. It is puzzling that I can only view this on the acrobat reader app on my ios device. Please advice how to view and/or extract full cover image.
