Thank you @didic! You're absolutely right, we need to be better referencing all the elements at play here. One thing we're looking to develop are more opportunities for Steemian artists to take part in illustrating our articles. I guess this isn't "open source" in the traditional sense - but perhaps there's something there the process of crowdsourcing artwork is a community endeavor.

We'll message you about that / discuss further :)

Thanks as always for your support and constructive feedback!
