You do, in the form of CSS Spriting, which is very widespread and recommended
by all major performance optimization guides.  It's an ugly hack, though -
background-position was never meant to be used in this way.  I'm helping with a
bug on an internal page right now where background-position rounds in different
directions at certain zoom levels, causing the sprited image to appear to
vibrate when you animate between the sprites - my best suggestion so far was to
use <canvas> to sprite the images instead. ^_^
