@ippopotamos thank you for the suggestion. We do require that all images submitted for inclusion into the deck be appropriately cited, and preferably open-source. Anything copyrighted, or similar, prevents our including it in the deck for the obvious reasons.
More information about source citation, and suggestions generally, can be found here: AnKing MCAT Deck Submission Guidelines
Please let me know if you have any other questions. 
I created the image. So it’s free to use.
Got it got it, thank you.
Because of the way the website works I can’t retroactively edit this image in to replace the one in the existing suggestion, but if you want to resubmit a new suggestion with this image happy to take a look at it.
Will do.
Also pipopotamo is a fantastic username, btw.
Thanks! Haha
