Wow, I just stumbled upon this and it was so beautiful I had to share:
Thanks to Tibchris on Flickr for posting this (and making it available with Creative Commons).
If you’re looking for freely available images for presentations or in-class use, there are two great places to look:
- Wikimedia Commons images are all licensed under Creative Commons, and some (typically those taken under the auspices of the federal government) are public domain. Lots of search capabilities.
- Flickr also has a lot of images, but not all are Creative Commons. Go to the Advanced Search screen and select “Creative Commons” at the bottom.
Lots of beautiful shots on both these sites — I use them all the time for this blog and professional presentations.
Here are some more because they’re so pretty. Click on the link to see the license and original.

And an image of snow crystals, also in the public domain (from the US Agricultural Service)
And a red-headed rock Agama (GNU license by Chris Huh).
