This is part of the reason png is seen as a nice format -- it has taken strengths from both jpeg and gif formats. Unfortunately, it doesn't compress as much (in tests I've done, pngs of images tend to be larger than an equivalent jpeg), and older browsers (read Netscape 4, IE 4) don't read them. (Somebody correct me if I'm wrong -- but some of my clients use older versions of each of these browsers and cannot see pngs.) --Matthew -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Writing GIFs
I realize I am a terrible person for wanting to violate Unisys's patents, but I'm working on a web site that I think will often be visited by people with old browsers (it's the site for the elementary school my daughter attends), so rather than use PNGs, I think I'd be better off with GIFs. GIMP 1.2, even with the gimp-nonfree package, seems only to read GIFs, not write them. Does anyone know of a good, free-at-least-as-in-beer Linux program to translate PNGs and/or BMPs to compressed GIFs? If not, I guess I'll have to use Microsoft Photo Editor on Windows...

Thanks, Craig Actually, Gimp _does_ write .gifs. They just force you to type in the file extension yourself, and then they'll prompt you for the .gif options, including animation and all that. Works great on my Woody machines around here (well, as good as something can when there's a company like Unisys holding a patent on the technology :-).

The JPEG encoding isn't very good for text and line art. If you turn compression on the JPEG to 0, it'll work but then the size would likely be greater than a comparable GIF or PNG.
