This has been resolved over on Stack Overflow. For anyone interested, see http://stackoverflow.com/questions/39195891/wordpress-meta-box-plugin-retrieving-image-url-from-custom-post-type?noredirect=1#comment65738735_39195891

Brilliant, thank you, I really appreciate that.

When I add:

add_image_size( 'flexslider-thumb', 167, 119 );
add_image_size( 'flexslider-main', 757, 454 );

To functions.php, then use those size names in the flexslider code like this:

$images = rwmb_meta( 'swso_prodImage', 'type=image&size=flexslider-main');
foreach ( $images as $image )
{
   echo "<li><a href='{$image['full_url']}' title='{$image['title']}' rel='thickbox''><img src='{$image['url']}' width='{$image['width']}' height='{$image['height']}' alt='{$image['alt']}' /></a></li>";
}

Then re-upload the images, it all works fine.

I do have another question though. The link to the full size image adds “/undefined” to the current page URL rather than actually linking to the full size image. Any ideas what could be causing this?
