Shouldn't be a server problem because CB Captcha works on other sites on the server.

Quoting myself seems odd but anyways....

I ended up installing Captcha 2.0.1 and my image still does not show up. It doesn't show up in the back end either.

Still awaiting a reply, this thread seemed to die right after a I posted.

To show up the image with security code you only need to set session handler to None in joomla system configuration. I think it's set to Database by default. I change it to None and that's helped me.

I am having the same issue. The security image is not showing up neither in the back-end nor in the frontend. Here is my setup:

Joomla 1.0.13
CB 1.1
Captach Plugin 2.0

I have install the cb.captcha but I can't see the image on the front page. The url from tha image is the following.

www.xxx.com/index2.php?option=com_comprofiler&task=tabclass&Itemid=1&tab=getcaptchatab&no_html=1

I have already install the GD Gallery and the configuration of PHP file is the right as you have mentioned.

What can I see for checking that?
