The fromstring/tostring methods simply ignore the palette, and in
0.2b4, there's no clean way to attach a palette to an image. So the
quickest solution is probably to convert the image:
if im.mode == "P":
im = im.convert()
out.fromstring(im.tostring())
(convert without an argument converts to the palette mode, or copies
the image if it isn't a palette image in the first place).
I'm working on better palette support for 0.2b5 (still not sure if/how
palettes should be handled by tostring/fromstring, though). You may
also wish to take a look at the palette patches Anthony Baxter sent to
this list a while ago.
