How do you cite some commonly circulated image on the Internet with no source Pretend that there is some image on the Internet that is commonly circulated, like a meme template involving a picture of someone's face. If the original thing had no source, but one (for whatever reason) needed the image and its citation, how would one try to cite the image?
I would cite such a source in the same way as an anonymous or unknown author's work would be cited. You should consult whatever style guide you're using for your current manuscript.
