Well, I have the very same question and just joined to see what happens! Also there are sites like www.guardster.com that when you enter a URL in them, they hide the address from the proxy servers that ban some certain sites and they can read all the contents of the site. Of course reading the contents is not such a special thing, but then they can display the images of that site too, it's a very different thing, coz they should use the original address of that image, so, if they don't change the address, the pic won't be displayed, but now it IS displayed! Is it something magical with PHP that we can have such effects?!
