Oh, btw. This happens with all my books. I remember Google play books used to behave this way until the updated it, many months ago, and now it shows up fine. That's why I think it's a reader problem and not a book problem.
It might be that other devices are overriding the size specified by the publisher. The problem with that is there is no way for an algorithm to know for sure what size the publisher intended, it requires some human judgement. Should it be relative to the screen size or to the font size? Did the publisher intend to have images 100% of screen height but only tested on a 600x800 screen, or did they intend 80% but only tested on a 758x1024 screen? Any automatic resizing algorithm is going to make some mistakes.

I think this is the same issue for a lot of other aspects of ebook display: does the device override the publisher's settings, which make books by bad publishers look better and books by good publishers look worse, or do they respect the publisher's settings so that books by bad publishers will look bad and books by good publishers will look good?
