First off, I just got this plugin and love it. It is great for customizing output and maintaining image style across a whole site.
The one problem I keep running into though is it seems the code snippet in the documentation to call just the url of an image does not work, this code in particular:
kd_mfi_get_featured_image_url( 'featured-image-2', 'page', 'full' );
I have not been able to get this to put anything out even standing on its own. Is there a better way to do this? Basically what I am trying to do is have the URL of the uploaded images be set as backgrounds so I only need the URL.
Any ideas would help. Thanks.
