Flickr Album - HMTL Inside Markdown?

How can I render a Flickr album in Hugo? Flickr provides this code. However, it does not render in Hugo if I insert this into the body of the post.

<a data-flickr-embed="true" href="" title="Gamification Frameworks and Concepts – Kevin Werbach – Visual Summary"><img src="" width="640" height="480" alt="Gamification Frameworks and Concepts – Kevin Werbach – Visual Summary"/></a><script async src="//" charset="utf-8"></script>

Are you inserting the HTML code in Markdown content directly? If so, the raw HTML code will be omitted by default, unless you turn on the markup.goldmark.renderer.unsafe as true, see Configure markup | Hugo.

You can also create a shortcode for this without changing the configuration, see Create your own shortcodes | Hugo.
