That article does not have the proper Open Graph tags on the page. I do see an Open Graph description tag on the page, but it's probably more generic than you're looking for:
<meta property="og:description" content="Noticias de Latinoamérica."/>
To read about how to add og:image tags and og:description tags please see our
documentation page here
. The easiest ways to do this would be to 1) Create an Open Graph object or 2) add the SCOpenGraph easy-tag, both described at that documentation link.
After the tags show up, please keep in mind that you will need to force Facebook to re-scrape your pages using the
Sharing Debugger
or you can also do this using
our Social Debug page
to do this too.
