That's because you haven't constrained top and bottom. The following fragment works in a 2004 version of Mozilla and even Mozilla 0.9.1 from 2001! (Inline styles used for ease of demonstration, not as good practice.) <div style="position:relative; width:25em; height:25em; background-color:green"> <img div style="position:absolute; width:10em; height:10em; top:0; bottom:0; margin-left:auto; margin-right:auto; margin-top:auto; margin-bottom:auto; left:0; right:0; background-color:red" src="Summerpalace02.jpg" alt="arbitrary image for demo"> </div>
