Is it possible to access or set individual pixels of an image?

[Marty Billingsley]

Thanks to everyone who responded! I understand imageData a lot better  
now. (And the fact that transparency is stored in maskData, not  
imageData.)

Turns out I was able to solve the problem using a combination of crop  
and imageData -- now I can split an image into irregularly-shaped  
puzzle pieces.

Next step: snap a photo with the web cam so the photo can be turned  
into a jigsaw puzzle.

Thanks agin,
