I’m using GP Premium and WP Show Posts Pro. I’m trying to determine if there is a way to display the caption field from the media file below images so I can give proper attributions. Can this be done simply for featured images or do I need code? Thanks

Hi there,

You can use this function: https://developer.wordpress.org/reference/functions/the_post_thumbnail_caption/

Then you’d need to hook it into the list. What location are you using for your featured images at the moment?

Thanks for the quick response. Sorry for my slow one. I’m using my featured images in Posts, Show Posts and headers. My main concern was Post and Show Posts. I assume I create a hook, is that correct? I am a bit of a newbie here so forgive my ignorance.

So are you wanting to display the caption with all featured images on your site – theme and WPSP?

Yes. That is correct.

You could try something like this:
```
add_filter( 'post_thumbnail_html', function( $html, $id ) {
    $caption = get_the_post_thumbnail_caption( $id );

    if ( $caption ) {
        return $html . '<div class="featured-image-caption">' . $caption . '</div>';
    }

    return $html;
}, 10, 2 );
```

Thank you. I can take it from here. It would be fantastic if image attribution was a feature in your pending release of GP. I really like using GP. Just a thought.

Thanks again.
