Web pages can specify an image to be used as a preview for the page, for example the Open Graph meta tag:
<meta property="og:image" content="http://example.com/preview-image.png" />
This target states whether the article has an image specified.
When the article specifies an image the value will be
true, otherwise the target will be blank.
