I suggest you to use a different file for each image.
Remember: the height and width % are related to the parent of the DOM element where img is placed.
This is not usually a problem for the width, because left and right edge are the same of the ebook screen.
BUT this is a problem for the height, because the parent is the body, and the body height "begins" in first page of your chapter and ends in the last page of your chapter. So when you ask an height 90%, you are not talking about 90% of the page, but 90% of the body element, so 90% of the entire chapter!
