While so much is published about Image Protection and that Copyright is automatic and enough deterrent to prevent image theft and plagiarism, it assumes that everyone is honest and law abiding. But in reality, Copyright will only prevent large international companies from stealing your images and then only if they need to preserve reputation. This especially applies to search engines who index them to provide easy perusal and selection.
So rather than waste time trying to enforce take-down notices and sue entities that are usually no more than a domain name, why not use real image protection software, one that protects your images from absolutely all of the avenues of copy and exploit. In which case we can forget about the useless concept of no-right-click scripts and all of the content protection plugins available for WordPress and other CMS.
The ideal solution for protecting web content is the ArtistScope Site Protection System (ASPS) which will copy protect everything on a web page. However ASPS requires a dedicated server or VPS to install the module at system level.
But ASPS can be used on shared hosting sites indirectly.
Guest Video provides a copy protected web hosting service that includes copy protection. Those protected pages can be viewed directly or embedded into existing pages by using the WordPress plugin.
Or existing WordPress sites can use the SafeGuard Media plugin to add copy protected images, PDF or video to any web page or post.
