The links are sorted in order of appearance. Refgenerator is a 2 in 1 plugin in such a way that it can generate the

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.
