With most of the WordPress sites I develop, I don’t want the homepage to be the default blog page with a loop of posts. Luckily, there’s an easy remedy by setting the front page (under Settings -> Reading) to a page called Home and the posts page to a page called Blog.
That works great… at least until you’re trying to pull a featured image or custom field from the Blog page. Because of how it overrides the page template to be index.php, if you call the function the_post_thumbnail(), you’ll get the thumbnail of the most recent blog post instead of the page. Same goes for any other post functions like the_content() or the_permalink(). Here’s how I suggest getting data from your posts page.
