How to/Plugin for attaching featured images using the Media Library

Hi Guys,

I’m currently using the plugin CRED from toolset to create a custom Form Post page where a user can post content while not having to use the built in editor. I’m trying to get it so that when a user wants to attach a featured image that they get the built in Media Library popup instead of having to upload an image. I can’t seem to find a plugin that can do this nor instructions on how to manually add it.

I’ve found out how to call the media library but I can’t find documentation on what I need it to return and how to structure whatever it is so it can be posted along with the post.

Any help would be appreciated on this.

Thanks,
