thanks for feedback, it seems to work

i wonder if it would be desirable to call ppmtojpg or better ppmtopng
(hmm, there is no ppmtopng, why not? there seems to be ppmtogif)
automatically if installed.  or write it in pure emacs lisp.

here you see the ppm file contents as emacs-framebuffer works only in
framebuffer so far.  i think that it should be possible to support xterm
too because w3m browser is able to show pictures even in xterm, but i
haven't got around to this use-case as i am mainly after eliminating gui
dependencies
