It doesn't require any plug-in, if your browser is Java-enabled.
The way it works is:
- Once the html page is loaded, then it will request for a Javascript code from the server.
- After it was loaded and executed, then the script will send html source URL and requesting for an applet.
- The server then compare that URL with the one set by image owner.
- If the URL is OK, then the server will send the image ciphered and bundled inside a Java applet.
- This applet will decipher the image and display it on screen. It disable mouse right-click and detect the PrintScreen button.
So the image will never be written into any separate file.
The only way to steal the image, is to take photo of the screen
or grab it from the display card's memory.
This method shows that by using just a Java applet can do the job. No need any proprietary software component to be installed by the viewer, just a standard Java Virtual Machine will do, which most web-browser already have (don't know about IE 6).
