Related Posts Plugin with Photo Thumbnails (WP)
This is a very fine WordPress plugin (available for other platforms too) to display related posts BUT – with photo thumbnails. You can choose to display this gallery type related posts thumbs with little info about post, in the single post. You just go to the website, tell them your blog address, thumbnails quantity, email and get the plugin. Install it and you are ready to go.
Show related stories from your blog under each post with thumbnails. LinkWithin is a blog widget/plugin that appears under each post, linking to related stories from your blog archive. Don’t let your past stories go to waste. 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. You do not need to add additional custom field for thumbnail images. This will definitely increase your blog’s pageviews and keep readers engaged. The widget links to stories that are relevant and interesting to readers of a particular post, keeping them engaged with your blog, and increasing your traffic.
