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).
This plugin is available for download to be used on your WordPress self-hosted installation.
