Hi, I'm new in ZenPhoto so I need a little help, in my website Site I want to post a comment but in any captcha image show me the error 'Captcha verification failed.'. So I want to disable it but I can't find the option. Thanks for your help.

The option is found on the options, theme options tab. However, the theme must support it, so you need to be running one of the distributed themes to be sure of seeing the option.

hey, thanks, now is working good!!!!

You are not the only one who has had trouble finding this option. The next release will redact the option to the comment options and remove the theme dependencies.
