First, I would like to thanks for your effort on this useful plugin.
May I know how to add the right click notification? It means when user right-clicked on the image, then it will pop up a notification msg telling user that the right-click has been disabled.
Instead of customizing the code manually, I do hope you can create an extra function for this plugin, so that it will able for us to customize the notification msg via the backend.
Hope to see the updates soon.
