Current image processing rules are in mozilla/page-metadata-parser /parser.js:40-46:

  image_url: [
    ['meta[property="og:image:secure_url"]', node => node.element.getAttribute('content')],
    ['meta[property="og:image:url"]', node => node.element.getAttribute('content')],
    ['meta[property="og:image"]', node => node.element.getAttribute('content')],
    ['meta[property="twitter:image"]', node => node.element.getAttribute('content')],
    ['meta[name="thumbnail"]', node => node.element.getAttribute('content')],
  ],

Current meta tags for https://en.wikipedia.org/wiki/Katie_Ledecky via meta-scraper:

`$ meta-scraper -u "https://en.wikipedia.org/wiki/Katie_Ledecky"`

``` html ```

Sadly, doesn't look like any tags we can scrape that match our page-metadata-parser rules in https://github.com/mozilla/page-metadata-service/issues/85#issuecomment-243200450
