No Right Click Images Plugin - Version 2.1

Version Description

  • Added option so that logged in users are allowed to copy images. Disables the plugin for logged in users. Captured copy to clipboard events to prevent another way of copying in some browsers. Fixed a problem in image replacement that prevented an image from being restored when another image was right clicked before the image times out.
