Here's the process I used to determine the maximum image size:

  • Create a 1024x768 file with alternating blocks of 1-pixel lines, making it easy to spot resizing anomalies
  • From that file, create a 128x768 horizontal strip and a 1024x128 vertical strip
  • Create an epub with these images in different chapters
  • Compile the epub with Kindle Previewer (or Kindlegen)
  • Transfer the generated .mobi to a connected Kindle /Documents folder
  • Open the .mobi on the Kindle
  • Take a screenshot of each rendered strip (on the PW, touch upper right and lower left corners at the same time)
  • Open each screenshot in an image editor, measure the rendered area
  • Create an image with these dimensions (940x658)
  • Add an image of that size to the epub, recreate the .mobi with Kindle Previewer
  • Confirm lack of resizing anomalies on the Kindle with a magnifying glass
