At the slight risk of posting a bit too often in these threads - I know of
2 social integrations which allow pictures and one crawler-y piece of

Facebook OpenGraph tags (just pasted from an app I contributed to, or for
some more info there seems to be a reasonable blog post

<!-- Open Graph tags for Facebook -->
<meta property="og:title" content="Directory of Open Access Journals"/>
<meta property="og:url" content="https://doaj.org" />
<meta property="og:description" content="DOAJ is an online directory that
indexes and provides access to quality open access, peer-reviewed
<meta property="og:image" content="

Twitter cards with a picture (
https://dev.twitter.com/cards/types/summary-large-image ):

<meta name="twitter:card" content="summary_large_image">
<meta name="twitter:site" content="@nytimes">
<meta name="twitter:creator" content="@SarahMaslinNir">
<meta name="twitter:title" content="Parade of Fans for Houston’s Funeral">
<meta name="twitter:description" content="NEWARK - The guest list and
parade of limousines with celebrities emerging from them seemed more suited
to a red carpet event in Hollywood or New York than than a gritty stretch
of Sussex Avenue near the former site of the James M. Baxter Terrace public
housing project here.">
<meta name="twitter:image" content="

DublinCore (DC) metadata - incidentally that seems to already be there on
pages, incl. FOSDEM homepage:

<link rel="schema.DC" href="http://purl.org/DC/elements/1.0/" />
<meta name="DC.Title" content="Welcome to FOSDEM 2016"/>
<meta name="DC.Format" content="text/html" />
<meta name="DC.Language" content="en" />
<meta name="DC.Subject" content="FOSDEM 2016" />
