Is there a good place on usenet to post images relevant to sci.astro and
sci.geo.geology. In my case, I am thinking of images of Mars rocks, but
there will be plenty of geological/astrological images of interest to
people.

Tell me you didn't mean to write astrological.


Is there a policy against attachments here?

Yes. This is a text only newsgroup.
Post your images to the alt.binaries.pictures.astro
