I had an e-book which had 2 image files, both "claiming" to represent the cover image. Only one of them was actually marked as being the cover image, the other obvious not (not even possible). Check Book indicated no problems.
However it turned out that the image which was marked as the cover image was not used at all (nowhere in the e-book), and the other (unmarked one) was really used as the cover.
Should Check Book not indicate that the unused image file is "unused" even if it is just marked as being the cover image?
