Related Posts Thumbnails Plugin for WordPress

Related Posts by WPBrigade will add related posts thumbnails after the post. This Related Posts Plugin allows to customize thumbnail sizes, display settings and type of relation. By default it uses generated by WordPress thumbnail for the first image appeared in the post, that was uploaded on the server with sizes as set in Media settings. You can select between 'thumbnail' and 'medium' size options. In addition if your theme supports Post Thumbnails feature introduced in WordPress 2.9 you can specify custom thumbnail size. You can also specify post custom field name to be used as thumbnails source. Thumbnails are arranged in columns under the post with related posts title/excerpt under each post thumbnail. Colors of background, border, text, text sizes, background on mouse over, title and excerpt length can be customized. See screenshot. You can specify number of related posts to display, start date, categories to show on and to include, top text, style settings, default image URL. You can select type of relation - categories, tags, categories and tags, random or custom taxonomies. You can specify where to display related posts - choose page type (main or single), post type and select categories. You can turn off automatic appending to the end of post and use <?php get_related_posts_thumbnails(); ?> php tag in the Loop of your theme. Related Posts thumbnails sidebar widget is also available. You can use [related-posts-thumbnails] shortcode in the post body. ** This Related Posts plugin has Gutenberg block ** Contributions:
