11/3 - Flash Header Customization

We want the three images in the attached header (small ones on the right side of the flash header) to fade up and down constantly. Don't stop them. The motion/fading is continuous. One image should fade in, hold and then fade out. As that image is fading out, another image, randomly selected, should fade in. The fade up and down on each image should take about 3 to 4 seconds. That's it, very simple!
