Hello,

yes, TclMagick "should" work without Tk installed or X11, but I haven't been able to make it work that way neither.

for using the pragana simple build of Tcl-magick, yes, you will need ImageMagick installed, and its libraries installed in something like /usr/lib/libMagick.so.7

Hi everyone,

What do you think about use reCAPTCHA.net to resolve the Inaccessibility of CAPTCHA?

I've developed a package that use this service and can provide this check in ad_form.

Try to download it at: http://dl.dropbox.com/u/6061429/recaptcha/recaptcha.tar.gz

You need create an account at www.recaptcha.net and get the public and private key. After this, add this keys in /recaptcha/public_key.txt and /recaptcha/private_key.txt.

To use it in ad_form, add this line:

recaptcha::create -form $adform_name

and add a validate in ad_form

-validate {
        {recaptcha_service
                {[recaptcha::check -challenge_field $recaptcha_challenge_field -response_field $recaptcha_response_field]}
                "\"#<span>recaptcha.Title</span>#\" #<span>recaptcha.Error</span>#"
        }
}

In my blog I posted an image of this usage http://alessandrolandim.blogspot.com/2010/04/recaptchanet-no-openacs.html
