This is a really quick, easy and simple method of adding a featured image to wordpress pages or posts.
Simply open your theme’s functions.php file, go to the bottom, and just before the ?> paste this
add_theme_support( 'post-thumbnails' );
This will then enable the “Set Featured Image” option within WordPress.
How to get it to show in your theme?, paste this somewhere 🙂
