The plugin is an add-on for the Related Posts by Taxonomy plugin by author keesiemeijer: http://keesiemeijer.wordpress.com/related-posts-by-taxonomy/
That plugin allows you to show thumbnails or links of related articles in a sidebar. This works for a lot of types of content. For example: posts, products, etc.
Unfortunately, that plugin does not work for pages. This add-on solves that issue by creating taxonomies for pages.
