Reverse the check for http response code.
There are many codes other than '404' which indicate that the media file is not present or otherwise unusable. Instead of checking for a particular failure mode, check for explicit success. I ran into this on a server that had directory listing disabled, and returned a 403 (access denied) error on non-existant files.
