WordPress: How to Setup A Default Featured Image

A quick tip to setup a site-wide default featured image/thumbnail in WordPress:

function wp_default_featured_img( $html ) {
    // If there is no post thumbnail, return a default image
    if ( '' == $html ) {
        return '<img src="' . get_template_directory_uri() . '/images/default-thumbnail.png" width="150px" height="150px" class="image-class-name" />';
    }
    // Else, return the post thumbnail
    return $html;
}
add_filter( 'post_thumbnail_html', 'wp_default_featured_img' );

Simply add the above to your functions.php file and make sure the default-thumbnail.png file exists in your images directory and you’re done!
