not authorized to view CB Captcha image

I've been trying to get CB Captcha to work and think I'm really close. Bottomline, the image won't show on the registration page but the Security Code box does. If I look at the source of the page the image is written in there to display

[code:1]<td class="fieldCell"><img src="http://172.20.1.131/joomla/index2.php?option=com_comprofiler&amp;task=tabclass&amp;Itemid=1&amp;tab=getcaptchatab&no_html=1" />[/code:1]

so if I put that URL in the browser I get:

You are not authorised to view this resource.
You need to login.

The CB Captcha is set to be Public on the backend.

If I log in and try that URL, it goes to my user profile. If I fix the URL so that all the &amp; are just & then the captcha image shows perfectly IF I am logged in.

If anyone has any fixes so that it'll display the correct URL to display the image on the registration page when no one is logged in.

Obviously GD2 and FreeType are installed correctly if I can generate an image. I just need to make it publicly accessible.

Thanks in advance!!!

Hi, is there a resolution for this issue at all? I also am experiencing the exact same scenario.
