I take about 130 "fine" (best quality setting) photos, on my 256mb card. I can't remember how many it holds, though. Then, I would go to Walgreens, download them on the machine, and within an hour, pick up my cd for 3.99. Actually, I didn't pick up the cd until the next day each time, so I wouldn't have to wait. They didn't keep my card, and I didn't have to wait and burn the cd myself, like some machines do. If you print any photos at Walgreens, the photo quallity is superb! I was amazed!
Also, when I picked my cd up each day, I put it in the photo machine, to make sure the photos were on there.
HTH.
