I don't think you can transfer the picture from the computer onto the photo card. You'll have to save them to a disk.

I HIGHLY recommend trying Snapfish.com. Cheap, fast, great quality photos. Plus they are always e-mailing you free offers for prints. You upload the photos to the website, fill out the shipping and payment information, and a few days later they arrive in the mail. I was really impressed with my first order - my kids' prom pics. Over 60 pictures, and I didn't even spend $10. (including shipping) and the pictures came FASTER than I'd expected.
