Displaying the links to related posts along with a thumbnail of the corresponding post will help you increase the page views/user .Users will be tempted to go for the related posts when they are presented attractively with thumbnails.

This is another first release from me.This one also uses the media thumbnails generated by blogger for each post.

For displaying the thumbnails,this widget will use the images uploaded for the post using the blogger image uploader(from the post editor) [Update - Now supports external images also.]
