I don't think that $_FILES['type'] is really all that useful for getting
reliable information about a file, since it just trusts the browser/user,
which could be uninformed, misinformed, or deliberately dishonest. Either
pass the temp file to the unix 'file' command or peek inside it on your
own (check the 'magic' file that comes with the unix 'file' command for
details on what to look for).
