That’s because object properties are case sensitive, thus $post->ID is not the same as $post->id . Just by printing out these two you’ll notice the difference, or do a print_r of the $post object to see all of the available properties and methods.
How can we force has_post_thumbnails() to return false? Method #1 – disable theme support: You can remove the post thumbnails support from the backend, with function twentythirteen_child_setup() { remove_theme_support( ‘post-thumbnails’ ); } add_action( ‘after_setup_theme’, ‘twentythirteen_child_setup’, 11 ); but notice that this will not remove the featured images. If the _thumbnail_id post meta value is non-empty, … Read more

A simple $post = get_post( ‘some custom id’ ) which you might think is innocent, actually sets the $post object to the post … Read more
the_post_thumbnail is unfortunately named, because it suggests a small image but actually refers to the featured image of a post. Adding support for it simply makes the ‘featured image’ box available in your post editor. Now, if you look at the source code, you see that if there is no size specified when calling the_post_thumbnail, … Read more
the_post_thumnbail() doesn’t accept an arbitrary post id as an argument. It just takes a size to display. To get the post thumbnail URL of a given post, you need to use get_the_post_thimbnail_url(): <?php echo get_the_post_thumbnail_url( get_option( ‘page_for_posts’ ), ‘full’ ); ?>
