<P>
An indexed image is an image "compressed" in memory to occupy as little memory as possible in this sense it is slower to draw and only a single indexed image can be drawn at any given time. However, this allows images with low color counts to use as little as one byte per pixel which can save up to 4 times of the memory overhead.
