I'd try another web server-- Most standard web servers just strip off the part after the '?' and serve up that file (which is what we are looking for). I just tried the web server you posted a link to earlier (as well as looking at the source) and it doesn't strip out the stuff after the '?' so it is looking for the wrong file. Edit: The above is a bit of an over-simplification, but in general it describes the expected reaction of a typical web server to a URL with query parameters pointing to a file in a real file system.
