Media Library consists of the images, audios, videos and files that you can upload and add to the content when writing a Post or Page. Here you can view, add, edit or delete any media related objects if not needed.
Media is a tab in your WordPress admin sidebar which is used to manage user uploads (images, audio, video, and other files). Under the Media menu, there are two screens. Users can also upload media (images, videos, etc) while writing a post or page. However, the Add New link under allows users to upload files without attaching them to a specific post or page.
The biggest complaint about the media library in WordPress is that it is not organized. All media files are stored and organized based on the year and month they were uploaded in a folder called /wp-content/uploads/. You can search the media files by using your WordPress admin menu, but there is no way to store media files in specific folders. There are plugins that allow you to organize media files by using tags.
WordPress media editor also has some lesser-known features that folks don’t know about. One of them being the ability to edit images right from your WordPress admin area. Under the edit screen of your library, there is an option for photo editing that allows you to crop, resize, and scale images right from your WordPress admin area.
