LinkWithin is a widget that links to related stories from your archive under each story on your blog.
They retrieve and index all stories from your blog archive, not just recent stories, making them accessible to new or casual readers of your blog who would not otherwise encounter them.
This blog post recommendation widget not only display just a link it will display related post in a photo thumbnail.
I Have added this widget for my "Blog Catcher" Blog.Which works fine with Firefox,Internet Explorer and Opera web browsers.
So if You are a blogger or web site owner this free widget will be very useful for you.
