I've recently discovered that someone has stolen images from one of my virtual tours and is using the images for commercial purposes. I presume they used the "print screen" button. It's an easy way to capture a scene from a fullscreen virtual tour, and it gives you a pretty high-res image to boot.
In addition to putting a copyright message in the GUI of my virtual tours, I've been thinking it would be nice to make it a little harder for this kind of nefarious activity. Is it possible to disable the print screen button? Or is it possible to have a message popup if someone hits that button? Something like: "This image is copyrighted. Please don't steal."
I'm also assuming that these images are stored in the browser's cache, so even if the print screen button were disabled, they could still peer into their cache file and get what they want, right?
