Have not tried this FOR thing yet, but mentioning 'cmd.exe' triggered a
solution for my problem.
Post_Frame_Command=ppmquant -fs 256 %o | ppmtogif > gif.gif
does not work, nothing seems to happen.
Post_Frame_Command=cmd /c ppmquant -fs 256 %o | ppmtogif > gif.gif
works fine.
Post_Frame_Command=command /c ppmquant -fs 256 %o | ppmtogif > gif.gif
does not work. POV says: could not create process.
Is there something I can do to POV-Ray or my system (WinNT 4) that
autmatically cmd.exe is used?

But it can append to the existing name. So, for example:
D:\myfiles\POV>for %i in (*.bmp) do copy %i %i.bak
D:\myfiles\POV>copy dispersion.bmp dispersion.bmp.bak
1 file(s) copied.
D:\myfiles\POV>copy disp.bmp disp.bmp.bak
1 file(s) copied.
D:\myfiles\POV>copy sig000.bmp sig000.bmp.bak
1 file(s) copied.

Me too.

I am not. What I meant was that truly professional graphics work is
done on graphics workstation where 48 bit color is native.

And I have to agree that your definition of "professional" is unusual.
Almost all professional computer art is -not- done on such workstations.
Some of the best and biggest jobs are, but not any large percentage of the
total of professional artwork.

I know a girl who can draw a better sunset in MS Paintbrush (16
colors) than I would ever do in POV. But this is art, and I was
talking about work (although I have to agree that in CG the line is
quite blurred)

Aren't you able, in PNG, to specify the number of bits per color? Although
it only lets you go down to 5 bits per color, it's still pretty lossy :)

Is this possible in POV-Ray?

Yes, it is, though that is *not* what I was looking for.

Question about that: Is there a way to specify that it *only* use colors
from the Web palette when converting?

And how would I do that? Agent is *really* picky about colors- I think it'll
only work with the Web palette.

Looks like it doesn't. Instead it just wants the first and last 10 colors (20
total) to be the standard Windows/VGA base palette. As long as you don't target
8-bit display users, you are free to use whatever you want for the other 236.
But... if you are targeting 8-bit users, they do have a recommended palette to
go to (the office palette)
http://www.microsoft.com/msagent/downloads/assistpalet.bmp
Anyway, that's basically what we used to need to deal with in Windows
multimedia, and making a set of images to a single 8-bit palette containing
those 20 colors in the top and bottom 10 was a common thing.

Tanks!
I know you'll think me a complete idiot (and maybe I am), but is there any
way to get ImageMagick to do this automatically?

As far as I know, ImageMagick is a command line utility. (?)
If that is the case, you can write a "script" for it. A shell
script if you work with Unix, or a batch script if you work
with Windows (the .bat files or .cmd files you sometimes see).
This is not very complicated, but if you've never done that
before, you'll probably need some help or a book.

Well, I do know how to get ImageMagick to mass-process images, I just don't
know what setting to use to get it to make the first and last 10 items in
the palette the standard Win colors.

I don't know ImageMagick. Perhaps there's a newsgroup or
mailing-list dedicated to the usage of this tool?
