From Opticom Data Research:
Keep clicking the Escape button on your BlackBerry to view skin cancer images from credible Web sites (National Cancer Institute, skin cancer databases, universities). Each button click presents a new high quality skin cancer image, selected at random from these Web sites. The average size of an image is 30Kb. The system remembers which images have been viewed (even after you close the browser), so only new images are displayed every time the Skin Cancer Image Viewer is used.
