Many thanks to everyone who contributed to this discussion about .png files.
I just tried using them for the first time for screen captures and am very
pleased with the initial results -- 3K file size vs. 70K for .tif, with no
appreciable loss in quality of print output.

I do. I also use them on-line instead of GIFs. As you may know,
Unisys claims a patent on GIFs. This patent does not apply to GIFs
created in programs licensed to use the format, such as Adobe
products. However, many of the customers of companies that I work
for refuse to use GIFs on principle because of the claim, and a
vocal minority would complain loudly if the companies used GIFs. To
avoid the bad publicity, these companies routinely use PNGs instead.
About the only trouble you might run into is that software more than
a couple of years old might not support PNGs.
