How they do that?
 

Take a look at the page http://examples.pixelmill.net/9/10027

If after the page loads and you look in your temporary internet files, none of the graphical images or css files download.

Looks like a good way to protect your webpages, anyone know how that's done.

Yes, they are all Flash .swf files.
:glugglug

Very nice...when they disabled right click by java and encrypted the code, there was no easy way to tell that those were flash files

Yep flash

Actually, it's a little more involved then that. If you go to the page, then click view on your browser, then privacy report, it shows all the links.

Some of them are images such as http://examples.pixelmill.net/9/10027/images/logo.gif . Why wouldn't that be downloaded in the temporary internet files?

Very cool
