Yes, the image is being updated every time you follow the link on

www.companybattleships.com/callingpage.php

you can see that because 6 additional black squares appear on the image
each time you follow that link.

But in your other browser (the one where you arrive at index.php with
not referer) you don't see the latest image: compare the 2 and the
black squares aren't there.

So why is the latest image not being displayed if the headers are in order?

In the example you send, the 2 images:
This image does not set any extra HTTP Headers
and
This image has headers set to prevent caching

are identical, so doesn't that just confirm that the headers don't do as
they are supposed to when drawing in gd images?
