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.
There is Text_CAPTCHA at PEAR, but I haven't used it myself. I use my
own little code snippet.
That sounds intersting. Could you show me an online example of this?
This is an example of what my script outputs :

Source available if you are interested.
