If no featured image has been selected for a post, page, or custom post type, this plugin will assign the first featured image found from its parent, grand-parent, great-grand-parent, etc.
The plugin makes no permanent changes – simply deactivate the plugin to disable the automatically inherited images. 😉
Coded for Performance
This plugin uses the WordPress wp_cache_get() and update_meta_cache() functions for maximum performance and fully integrate with WordPress core functionality.
