I did see this before. The problem was that it did not work well on my mobile device (iphone), where as the link I provided does.
The Reel sample had the problem of moving the page at the same time it tried to rotate the image. The other link does fine, but it does not have any other content. I am not sure what happens if the the Reel sample is isolated in its own page and if the ortery software implemented in to a web page.
I also found AJAX-Zoom (http://www.ajax-zoom.com/), but that looks like a lot of work to setup. But it does protect images and seems to be a better implementation?
