Lock has been designed to save images and videos from piracy. The stack adds a transparent Lock to your website which deactivates the drag and drop and right-click feature on your website. This prevents nearly everyone from stealing your images or videos. They are no more able to drag digital media to their desktops or right-click save them to their hard drive disk.
Lock works fantastic with every kind of stack you use on your sites, even third party stacks from other developers are fully supported. And the best thing: there's nothing to set up, nothing to play around in settings. Simply drag and drop the Lock stack from your Stacks library to your existing Stacks site and you're all set.
