Wanted Small captcha

fastrod · #1 26-03-2009

Dear people,

I'm looking for a small captcha script, so a custom shoutbox to be secure.
Personally I have very much wanted, and maybe ten different scripts download and try out but all in vain. There was 1 that worked but it was so complicated with a form / script around that for me all is not clear.

It must be really small captcha, 2 or 3 control numbers are enough as he should come in a small space. He should be easy to install course. Myself have some knowledge of PHP so if a script is good and clearly will be problem.

Someone who can help me here?
thank you

A captcha is not necessary when you consider other ways.
I always use additional fields that I create css invisible. If any of these fields are completed, it is a bot. Works well and I've never had spam in this way

Zecho idea is to refresh! I have not really ever thought!

good idea Zecho

better than a GD image with letters and numbers to back you must validate!

much less work is just as effective!

But they will not smarter than bots that when they say that they are invisible fields blank. Because it seems to me that you are not the first with this idea and is already used in the large and then you that option so son bone processed hear.
