add stuff to the database

I want a character that is a cyclops. Firefly wont recogozne the term or the idea of putting a single eye in the middle of a forehead. I've tried just adding an image and then referencing it. No joy. I've tried adding an image an then editing it via generative but that tool is like using a shovel to paint. I get 90% of what I want (which is amazing, btw) but this one hurdle I can't seem to bypass.

thanks
