CSS Image Rollovers Without Preload

[ws] Fast Rollovers Without Preload | Rychl� rollovery bez nač�t�n�
Something I've wanted to work with for awhile, this looks like a nice implementation.

When using CSS image rollovers, two, three, or more images must be loaded (and often be preloaded for best results). We've got one image for each state (normal, hover, active, visited etc). Putting all states into one image makes dynamic changes faster and requires no preload.
