The id is required by Alexa's TOS. It works without and if you spoof a bad id or something bogus, but that's against their TOS. All of this code is in the URL zimlet so if somebody wanted to they could modify their own version.
The caching is done by the browser. We use a simple img include to fetch the thumbnail, which allows the browser to cache it.
