How to echo data after a WP_Query

Within your Query loop, using your image URL as an example, put this:

<?php $image_url = get_post_meta($post->ID, 'image-url-field', true); ?>

Replace “image-url-field” with the name of your custom field.

Then, also within that same loop, do this:

<?php echo $image_url; ?>
