@JSWolf, I beg to differ. Ref. w3cschools reference page for the height attribute:
Quote:

% Defines the height in percent of the containing block

So according to spec, if you stick an <img> with height:100% inside your <body>, you get... something strange, quite often an image which is as large as the rest of the body content.
If some readers interpret height% in terms of screen height, that's handy (I don't know what abberations Apple adhere to), but it's definitely not universal, and certainly not according to w3c spec.
