Well, as far as PNGs go, most browsers do support the format and have
for a few years now. I think there was some quirkiness with Internet
Explorer 4 and 5. I'm not sure if the issues with transparency got
fixed in IE 5.5 or 6. Anyway, even the older versions of IE should
support PNGs that don't have transparency. I'm not sure about IE 4, but
I know that IE 5.0 supports them.

Netscape has supported PNG since the early 4.x releases and Mozilla and
Opera always have. I haven't had any users complain about the PNGs on
my sites and some of them do use old software.
