Responsive images should behave in IE

Responsive images css code should not break on IE. Current code breaks sizing in older XP machines running IE 8.
This code should do the fix:

img { 
	max-width: 100%;
	height: auto; 
	max-width: none\0/; /* IE8 - IE9 overrides responsive images http://www.456bereastreet.com/archive/201202/using_max-width_on_images_can_make_them_disappear_in_ie8/ */
	*max-width: none;	/* IE7, removes max width  */
	*width: auto; 		/* IE7, removes responsive images  */
}
