Using My Images

Unless I say otherwise, all of the images I post here are created by me. I’m sharing them to help you and others learn, so please, USE THEM!

You don’t need to ask me to use them, but I would love if you could include a little note if you use them in a presentation or a project. That being said, if you want a higher quality version of any of the art on this site for printing, you can send me a message or email me at and I’ll see what I can work out (I’m usually pretty accommodating, however requests for high-quality-images-of-all-the-doodles-ever probably won’t be accommodated).


You’ll notice that the images have ugly watermarks. This breaks my heart but I’ve actually had images stolen and reposted as someone else’s in the past. It’s a scary world out there.

I am also currently accepting commissions if you need an image for a scientific or academic publication. My more polished work can be seen on my portfolio site

Also, I would like to say again that these doodles are purely for EDUCATIONAL PURPOSES and unfortunately have not been peer-reviewed. This means that sometimes there will be spelling errors or, worse yet, may be slightly inaccurate. I apologize, and if you see an error, please let me know and I’ll do my best to update the information!
