    I've been trying to use this code from the docs...

    $images = rwmb_meta( 'info', array( 'size' => 'thumbnail' ) );
foreach ( $images as $image ) {
    echo '<a href="', $image['full_url'], '"><img src="', $image['url'], '"></a>';
}

    Does the 'info' part mean the field ID? I've tried it that way and I cant make the image appear.

    so my custom field group field has an ID of "blurb_1". Inside this is an advanced image field with the ID of "blurb_1_image".

    Hi,

    The image_key is the field ID. It might be blurb_1_image in your case. You can share the code that creates the fields, I can help you to review your code.
