Now, having tried your suggested solution, I must tell you that *it did not
work*. So much for /your/ advice.

Here's the PHP I wrote:
 <?php
   header('Content-Disposition: attachment; filename="SixSpot_d.png');
   header('Location: http://merlin.puter.lan/~lpitcher/SixSpot_d.png');
 ?>
 <html>
 <head><title>Trial Sendfile</title></head>
 <body>
 <p>Did you get it?</p>
 </body>
 </html>

There exists, in the source directory, a PNG file named "SixSpot_d.png.
That file can be accessed through the (internal) url
http://merlin.puter.lan/~lpitcher/SixSpot_d.png'

The web page, above, fails to initiate a download or show the specified web
page.

Instead, the web browser (Firefox 5.0.1 for Linux) /displays/ the specified
PNG, instead of the specified html, and /does not/ initiate either an
automatic download into the configured download directory or the Download
menu itself.

Advice (from various sources including PHP.NET) conflict as to which headers
are required, and the order of steps to perform.

So, Thomas, got any more "advice" for me?
