I have been looking for a good solution to block downloading images on my site by visitors who can look into page html. Though all developers I met said that 'being displayed means being downloadable', this plugin solved in an unique way with encryption and token. I'd say that another advantage of this plugin is its simplicity. I didn't have to install any application to my host that might make it unstable. Better if I can customize watermark drawn on my images. I'm a satisfied user.
