It's simple. Take your preview images (what a handy idea from Polaroid!) and use a scanner.
I tried using my floppy drive once, but the pictures kept getting jammed and wouldn't fold up small enough.
Here's the long way around, but it works.
1. Take your Polaroid picture with your Polaroid instant camera.
2. Listen to the whirrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr sound.
3. Smile when the camera burps out a picture.
4. Take the picture and hotglue it onto the front of your roommate's plasma tv.
5. Set up a digital DSLR with a macro lens on a stable tripod.
6. Move the DSLR outfit you've put together up to the hotglued Polaroid picture.
7. Remove the roof of your house to let in maximum light. Take your time.
8. Launch a space vehicle with a Christo sized fabric artwork inside. Summer is the best time.
9. Release the Christo artwork in space, using the simple auto-unfold directions.
10. Wait until the fabric artwork floats in front of the sun to diffuse the light. Listen to the neighborhood saying, "Oooh, ahhhh, or WTF?!?!?!" as they look into the sky.
11. Set the camera to a low ISO to maximize the quality of your image.
12. Take seven digital images of your hotglued picture. Nickname them "Sleepy, Dopey, Doc, Happy, Sneezy, Grouchy, & Bashful."
13. Connect the digital camera to your computer with the OEM USB cable.
14. Use the OEM installed software to download the images.
15. Chose a number between one and seven.
16. Keep the image that matches that number and delete the rest.
17. Get a job flipping burgers until you can afford Photoshop.
18. Take a night course at your local community college until you are "one with Photoshop".
19. Process your image in Photoshop, clearing up any digital noise, and deleting the angry reflection of your roommate as he discovers what you've done to his plasma t.v.
20. Have the hospital where you are staying arrange to make prints from your project.
It's so easy, a caveman can do it.
