I use the captcha 2.0 plugin on two b2evolution installations. On one installation everything just works fine, but on the other one there is no captcha image displayed in Internet Explorer (I've tested with IE7). There is a captcha image displayed in Mozilla Firefox though.
I have now found out that it works fine (the captcha image will be shown) if cookies for this site are allowed. But the strange thing is that I didn't disallow the cookies for any webpages. And for the one site it worked fine immediately (no cookies are disabled) and for the other site it doesn't work (cookies are disabled).
Actually I think that the plugin is not really useful if I have to tell the webusers to change something with the privacy on internet explorer. Why does IE decide to disable cookies on some webpages? And is there any way to always make the captcha image work?
