WP Lynx allows you to create stylized links akin to those in Facebook. These stylized links, known as lynx prints, can contain a thumbnail image of any of the images on the linked page, plus a short excerpt from the page. The images are automatically cached on your server (no hot-linking), and the content is intelligently scraped.
Note: version 1.0.0 of this plugin requires PHP5.3 or newer.

Automagically adds Open Graph tags to your blog. Control how your posts and pages are presented on Facebook and other social media sites. No configuration needed.
When someone likes or shares your blog on Facebook, your header image is shown. If someone likes or shares a post, the featured image (post thumbnail) is shown. If you haven’t selected a featured image, then the plugin looks for the first image inside the post. If there aren’t any images in your post, then your blog’s header image is shown.
