7189A

Key:

B&W, 500x789 resolution (or slightly less), 8k-22k file size
These are a little rough, but often good enough. I make no guarantees

16 greyscales, 500x789 resolution (or slightly less), 50k-120k file size
These look great on my monitor. Your monitor may vary

B&W, 2000x3150 resolution (or slightly less), 70k-200k file size
Just right for laser printing

The hi-res images may cause Netscape to crash. If you have this problem, then configure Netscape to use a different viewer for gif images. LView is free and works well. Look for it at Simtel
