In this post, Jeff Chandler explains a few changes to the Image media library that is expected to be in WordPress 4.0. WordPress 4.0 is expected to ship by the end of August and contains 2 subtle image to the image data in the media library. You can view the author who uploaded the image. Although you can view the parent post ID on the image attached to it, you cannot locate each post the image is used on. It is important you understand the difference between attached to a post and using an image that is already available in the library.
