stream will be output directly. To skip the filename argument in
order to provide a quality argument just use an empty string
(''). By sending an image/jpeg content-type using
<A
HREF="function.header.html"
><B
CLASS="function"
>header()</B

>, you can create a PHP script that
outputs JPEG images directly.
