This plugin can be used as a discrete but efficient tool for websites which have to make sure that copyright information for images is mandatory.
How it works: It simply blurs all uploaded images. The original only gets restored when the copyright info is set. 
The text field for the copyright info is provided as a form field in the attachment details view.
A simple but elegant solution to enforce copyright discipline among authors and editors.
This plugin is compatible with the plugin “Enhanced Media Library” (tested with version 2.4.5).
