title: How can I add images/diagrams to API Blueprint?
body: <p>We would like to integrate images into our API documentation on Apiary, as a way of documenting the underlying application architecture or to illustrate sample workflows/sequence diagrams. However, a search through <a href="https://docs.apiary.io/" rel="noreferrer">Apiary documentation</a> and the <a href="https://github.com/apiaryio/api-blueprint/blob/master/API%20Blueprint%20Specification.md" rel="noreferrer">API Blueprint Specification</a> don't seem to yield any results on how this can be done.</p>
  
  <p>Is it possible to add images to API Blueprint? Or do these images have to be hosted externally and referenced by URL?</p>
