Richard is correct with such a complex formula as jpeg simply reducing

colors does not guarantee a picture that will compress better in Flash

(or any JPEG encoder). But, this is primarily because color reduction

can actually increase overall image complexity. Less colors are

irrelevant to JPEG, only the resulting increase or decrease in overall

complexity of the image.
