Description:
------------
To prevent spam bugs (spugs? ;-) posted through the "Report new bug" form such as : 
http://pear.php.net/bugs/bug.php?id=7087

there is a need for a CAPTCHA mechanism as on the "add comment" bug form.

However, bertrand Gugger mentioned on pear-dev a problem with PEAR's CAPTCHA images and screen readers : 
http://beeblex.com/lists/index.php/php.pear.webmaster/4901?s=l%3Aphp.pear.webmaster
(looks like the "add comment" captcha is non-screen-reader-compliant in this regard. Neither is the "Request account" one...)

What about a non-graphical CAPTCHA as experimented in Phorum :
http://www.phorum.org/phorum5/read.php?16,54054
?

Hummm... not an easy one ;-)

Maybe better:  audio captcha. There's a PHP library for this ...

Visual and audio CAPTCHA generation class :

I tend to believe an alternative way would be to request a mail confirmation, as when you subscribe to a list.

I will add a non visual captcha (plain text, readable) while changing the other captchas.

Added new numeral captcha, see public_html/bugs/include/NumeralCaptcha.php for more details.

Thanks
