I'm getting good results with:

}

on Sigil and eReaders.

Let's say the image was the cover. That code would not work well at all. In fact, it's the wrong way around. For the cover, you want the height to be 100%. Also, if it's a map, you also want the height to be 100%. In a number of cases, that's backwards.
