Extend the REST-API to work with WordPress Media-Library. Organize images in Folders. Add and Update images including Metadata and Posts using the images. Access with Authorization only. 
This plugin extends the REST-API of WordPress to directly access the Media-Library for Images. It is intended to be used together with a Lightroom Plugin or as a stand-alone interface for headless WordPress. The new REST-API endpoints (functions) allow to add additional metadata to images, update existing metadata or update images completely without changing the WordPress-ID. Images may be added to the standard directory hierarchy of wordpress or to an additional folder which allows better organization and searching for images.
