*Ø* Public domain: some links

Just a few cool Public Domain (copyright free) sources I've been using lately, and a drop in the ocean of PD material online. I include US government agencies because, according to Wikipedia, all images published by the USA government are public domain. I presume this means unless otherwise noted. I've been finding plenty of great space shots at NASA.

Sorry, I'm too sleepy to categorise them. Use the following at your own risk:
