I'm writing a set of notes on topology that I'd like to share under the Creative Commons. Does anyone know where to find diagrams for links (not the Borromean link, I have that already) that are either in the Public Domain or under a Creative Commons license? It's for the knot theory section.
Most images from the Wikimedia Commons are either in the Public Domain or are licensed under the Creative Commons Attribution-ShareAlike 3.0 Unported License.
The links should preferably have many components, be "asymmetric", and hopefully most of their components can be knotted as well. A table of such links would be great but I'd be grateful for even one! The only "freely licensed" images I can find are of very simple links.
Edit:
In the end I gave up and made my own link drawing by editing together different knots. But still I think the original question has merit.
I am not sure about what "freely licensed" necessarily entails, but LinkInfo is quite a good table as far as links go.

It is run by Charles Livingston and Jae Choon Cha. I imagine that as long as you cited where you got the images from it would be fine.
