I want to get the featured Image URL of Blog Post

[Sunny Kumar]

Hey,

I need to get the featured image URL of blog posts and then create a wp_head hook element with the below content…

<link rel="preload" as="image" href="<image URL here" />

Can you please guide me to add this to my website?

Hi,

You can get the featured image URL by using the get_the_post_thumbnail_url() core WordPress function.
Reference: https://developer.wordpress.org/reference/functions/get_the_post_thumbnail_url/

Try this snippet:

add_action( 'wp_head', function(){
$featured_img_url = get_the_post_thumbnail_url(get_the_ID(),'full'); 
echo '<link rel="preload" as="image" href="'.$featured_img_url.'"/>';
});

Thanks, the code works perfectly.

I’m closing this support thread.
