I have done similar work, and i recommend you keep this simple. jpegs are
universal, the quality is fine and you can fit hundreds on a cd. I
recommend using photoshop, but if you don't have it you can use a more
basic imaging software to adjust and crop the images. Jpegs will work in
any software, on any platform you will need. Scan and save high resolution
(I would go over 600 dpi) You can always adjust later, but the kids should
start with high resolution or they will never get a good image. This is
especially true if they want to zoom in on one part of an image, not just
use the whole. The few seconds of delay in opening the image is with it.
and you'd be surprised at how nice images can come out of even a cheap
printer and cheap scanner. As far as naming the files, just don't have
spaces in the names, use dashes or periods. then there should not be a
problem on either platform.

Also, once a file is on a cd, it is there, it does not go away unless the
cd is physically damaged. and cds are really cheap. Make several copies.
experiment with the scans and printing on a basic inkjet and you'll see the
differences. just don't worry so much about memory, cds hold alot.
