Hey,
I started using your plugin today and noticed it doesn’t really support using the thumbnail caption… with the normal thumbnail you just do this:
Image: <?php the_post_thumbnail(); ?><br>
Caption: <?php echo get_post(get_post_thumbnail_id())->post_excerpt; ?>
But I ended up having to do this to get the caption from a secondary featured image (note, I’m using this on pages):
$second_thumbnail_id = get_post_meta(get_the_ID(), "page_secondary-image_thumbnail_id", false);
$second_id = $second_thumbnail_id[0];
// The thumbnail caption:
echo get_post($second_id)->post_excerpt;
I guess what’s needed really is for you to make get_post_thumbnail_id() return the post id for the thumbnail if you can.
Btw, love the plugin, made my life easier!
