If your image is 500 pixels by 500 pixels, but your IMG tag has "height=250
width=250" attributes, Netscape, MSIE, and probably a number of other
browsers will scale the displayed image to fit the specified dimensions. 
This is arguably a mild abuse of the height and width attributes, and there
isn't any guarantee that all browsers will honor those attributes when they
disagree with the actual image, but that's what's going on.
