I have to spawn an external program to view PNGs as opposed to automatic
inline viewing support in Netscape (this is a minor irritation). Secondly
the program I currently have associated with PNGs under windows crashes
whenever someone posts a progressive PNG (which means I can't view it
period when this happens).

Ah - this would seem to explain the problem. PSP has no options with regard
to super-sampling. I'll get hold of cjpeg and see if it fixes those
occasional images that don't respond well to standard jpeg conversion.
I'm a great respecter of file-size in posts which, all in all, is about the
only justification for jpegs. To be frank, given the POV is a fairly
technical, graphics orientated program, it seems hard to have much sympathy
for those who haven't got around to solving any technical problems to
viewing png's in this group.

They're not OK with me either. I can view them in my news-reader easily, but
I never download them at all because they're too big. I don't mind some jpeg
artefacts.

the larger size of png's is ok with me. but I guess some people still pay
for internet by the minute or something crazy. It may be best to post a jpg
for size sake, then include a link to a png version.
On a side note, I've had good results with the GIMP when saving as png's.

Sorry for following up on my own post, but I have been browsing a bit on
www.libpng.org after posting.
Interestingly enough, there is now also a "JNG" format, which
encapsulates a JPEG stream in a PNG or MNG file format. Haven't looked
at it in detail, but this might be a way to combine the good compression
of JPEG with features (like gamma correction, gamut specifications,
alpha channel) of PNG and also use it for animations (in MNG).
See http://www.libpng.org/pub/mng/spec/draft-jng.html for details.

Interesting. Netscape has had PNG support since early 4.0 releases,
IIRC. It doesn't support all features (e.g. no alpha channel, and I
think, no gamma correction), but should be able to display "normal" PNGs
about as well as JPGs.

_Some_ people? I wonder...
But I admit it's crazy.

Some countries - namely the UK - charge per the minute for local phone
calls, so for example a Brit might have "unlimited net access" but still
end up paying for the time spent online.
And I'm pretty sure that if it wasn't forbidden by law, the north
american phone companies would gladly do the same.

Fine with me.

lucky for us some companies are finally offering true unlimited access with
no phone bill :)

Well, I've had off-peak (weekend and evening) toll-free access for a few
months now. I'm only just learning to let this influence the way I use the
net. I still tend to plan my online access before logging on, so as to limit
my time online.
That aside, small file size is still appreciated. I'll wait five days for a
render, but it doesn't seem to have improved my patience elsewhere.
