My featured thumb is an external image on my posts, so the size arg/val isn't working in my shortcode. However, I do have another image url in a custom field that I would like to show instead.
I know how to show the custom fields via the shortcode, but I keep getting just the url since I don't have "img src" included in the right place.
Can anyone offer advice on how I can show an image from a custom field? (Either in place of the featured image or in addition too?)
