I am getting a list of all the images the following way:
$the_query = new WP_Query( array( 'post_type' => 'attachment', 'post_mime_type' => 'image', 'post_status' => 'inherit', 'posts_per_page' => -1, ) );
But I’m trying to get only those who are uploaded to a post on my website.
Not images attached to a specific post but exclude those who aren’t featured on any post.
