Troubleshooting Open Graph Image Tags on LinkedIn Previews

I recently had a problem getting LinkedIn to generate link sharing previews for a page. Here, the LinkedIn post inspector tool provides insight on the possible cause:

A search turns up another inspection tool which suggests the image size I am using does not meet LinkedIn’s requirements. A second search turns up an article that lays out LinkedIn’s required sizing of 1200px x 627px.

A quick resize later and I am off to the races.
