Well, not a diet, really. But seven new HP digital cameras now have a "slimming" feature built right into the camera. Select the pic, then apply as much slimming as you want. It really only squeezes the image horizontally, but the fact that HP saw a need for this speaks volumes. See http://www.hp.com/united-states/consumer/digital_photography/tours/slimming/index_f.html
