This technique can be very effective for improving site performance, particularly in situations where many small images, such as menu icons, are used. The Yahoo! home page , for example, employs the technique for exactly this Further Reading A List Apart published an article entitled CSS Sprites: Image Slicing's Kiss of Death which explains the concepts behind CSS sprites.
