Hi there, I am getting more and more emails through my webforms submited by bots. It looks like some sites liky yahoo are placing an image into their forms and the human has to enter a code visible on the image to submit the form. After some googling I found captcha, but I do not like the images. Do you know if there is a class available for PHP which does create the image and does parts of the handling? That seems like a common task to me. Maybe someone else already implemented such thing and can recommend.

You may want to try this class that comes with a CAPTCHA plug-in to do exactly that. The class comes with documentation and a straight example to demonstrate how to use. http://www.phpclasses.org/formsgeneration Here you may also find a screenshot of how it will look: http://www.phpclasses.org/browse/file/8244.html -- Regards, Manuel Lemos PHP Classes - Free ready to use OOP components written in PHP http://www.phpclasses.org/ PHP Reviews - Reviews of PHP books and other products http://www.phpclasses.org/reviews/ Metastorage - Data object relational mapping layer generator http://www.meta-language.net/metastorage.html
