Well since no one has any ideas I thought I would post this follow up
from my own efforts, in the hope that it might help someone else.
It seems that the captchas are actually working OK. The problem is that
the browser (iceweasel) that I have installed is not displaying the
artwork created by the captchas. I downloaded another php captcha called
jhfcaptcha which is self contained and may be run as a script via
Apache2 from my web site. It has exactly the same problem. It asks for
you to input the entry needed by the captcha to do its job...however
there is no box or any thing else that shows what I am supposed to type
in. I have checked the following:
GD is installed and working according to a test.php script that shows
what is going on. Php is also completely enabled and as many functions
as I can find are installed and enabled. I did notice that the
mime-decode function is not enabled. I will try that today.
In the mean time ANY IDEAS are appreciated.
I also tried from another computer using XP and IE7 and the only
difference was thate is a box with a missing image element icon in it
and you still can not see what needs to be keyed. The more I see of this
the more I think its a php issue are a graphics conversion problem.
