Hi.
I control some themes or plugins options with your metabox plugin. And i am happy with that:)
Every plugin or theme can have some their own metaboxes. So i am removing them and using your plugin the control these .
Sometimes these plugins or themes are saving meta values with different ways.
For example one of themes page title image background meta value option is saving value to database with image url. Not atachment id. So i cant control this with your single_image field.
For that reason i have asked this.
Thanks.
