Nikon updated the PROM for the D100. It was simple to do. I think they also did an update for the D70, but mine came with the latest version. The last time I tried, stores around here still had a problem with 3000 x 2000 jpgs when printing at 4 x 6. The Nikons produce a jpg file of about 2.5-3.2 mbytes. The stores have no problem printing the 1.5-2 mbyte jpgs from my wife's Sony.
