Right-Click Warning Message
You can create a custom message that will be displayed when a visitor attempts to right click an image on your site. This message can say whatever you'd like, but we recommend letting the visitor know how they can contact you if they would like to use the photo they are attempting to right-click or right-click-save. It is best to keep the right-click message generic as it will be applied universally to all images on your site.
This message is only displayed for images that are right-clicked. To customize your warning message, go to the "Warning Messages" section under Locks and customize your message.
