I've seen one ebook from Apple where the cover image was close to 90% of the book size. Yes, it looked better when I looked at the cover image on my iPad but overall, was the change worthwhile? Not really since I really don't spend much time gazing at book covers.

Just for the heck of it, I converted a 4000x6000 image of decorative cherry blossoms to a 1400x2100 image. Dropping the jpeg quality to 75% when saving gave me a 185KB file. The original image clocked in at 13.4MB but then the camera is set to maximize quality when saving .jpg format -- I have to justify having dual 32GB cards in the camera somehow.
