When I was reading the comment of Marko Petkovic to the previous post, I’ve decided to recommend his site, Chemistry Pictures, where some interesting images can be found (at least for students and teachers). All of these images can be used freely since they are in the public domain.
Other interesting chemistry pictures resources:
- Chemistry and Biology Pictures (public domain high quality science pictures, mainly biology related)
- Classroom Clipart: Chemistry
- Science and Chemistry Images, Clip Art & Structures at About.com
