Including an image of a drawing rather than linking to one
One of the ideas we've discussed is to reduce the number of links to external drawings. It is better for the learner to see the image integrated in with the text.
I looked around for an openly licensed version of the Michelangelo drawing linked on this page. Didn't find the version in the link....but there are many others to choose from in the commons category drawings by Michelangelo
Would one of these suffice?
