pnm means Portable Any Map, as opposed to Portable PixMap or Portable BitMap
which are subset of "any".
You could use
pstopnm -ppm file.ps
which will produce a file file001.ppm.
You SHOULD be able to define a converter
\converter "ps" "ppm" "pstopnm -ppm $$i; mv $$b001.ppm $$o" ""
which will result in conversion from file.ps to file.ppm
but I think that the $$b (base-name) expansion of the converters code is
wrong. I think it is correct in the new code that hasn't made it into cvs
yet. I'll test.

It had it's own, much more horrible problems that we would NEVER be able to
overcome. The current solution will eventually become "perfect", by which I
mean that you will be able to display graphics in ANY format, so long as you
can define a converter from that format to a "loadable format". For now, we
use libxpm to load the graphics files into memory, which means that the only
"loadable format" is XPM. Thus, you must define converters from any other
format to XPM. Eventually, we'll use the qt2 or xforms built-in image loading
routines, so we'll be able to load many more formats directly and your
complaints will cease!
For now, however, you have all the power but you, personally, have to make a
little effort to use it. That is, you must define the converters.
The only current REAL show stopper is that loading takes a long, long time
and blocks the rest of LyX. We have code that overcomes this, but it isn't
yet in cvs. A day or so only...
Anyway, these are my formats and converters, defined in my ~/.lyx/preferences
file. Note that I have to remove the converters from
/usr/local/share/lyx/lyxrc.defaults for this to work. (Or from
$LYXHOME/lib/lyxrc.defaults if you are using a cvs version of lyx that you
haven't installed.)

Maybe.
