Are you looking for a way to get the featured image source? We have created a quick code snippet that you can use to get featured image source for the attachments in WordPress.
All you have to do is add this code to your theme’s file or in a site-specific plugin:
<?php $imgsrc = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), "Full"); echo $imgsrc; ?>
Note: If this is your first time adding code snippets in WordPress, then please refer to our guide on how to properly copy / paste code snippets in WordPress, so you don’t accidentally break your site.
