My name is Iorgoba, I work on a bussines website and i want to put a captcha on it. Please if you know where I found some good catpchas, free or paid (my budget is max.40$), let me know.:) :)

If you know how to code in PHP (or a similar language) you can code one yourself. You can use some free examples on the web as a start point.

Here you will find instructions on how to build a CAPTCHA using PEAR: http://phpsec.org/articles/2005/text-captcha.html

Resourceindex.com has a few php, http://php.resourceindex.com/Complete_Scripts/Form_Processing/ - depends on your needs though (i.e. audio/visual/etc).

If you use a Content Management System it will probably come with the functionality to do a captcha with little effort to code it on your part. Just copy and past where you want it to go. I'm not a programmer at all, so using the built in functionality of a CMS like this is great for me.

I use Expression Engine: www.expressionengine.com. Might be worth a look for you.

The only downfall to using a pre-made out of the box system is that the more widely used it is, the more incentive there is for someone to break it. It makes a lot more sense for someone to try to break the CAPTCHA of a mainstream CMS (like I think happened to the old vbulletin one) so they have access to any site using it than to target your site specifically if you use a custom version.

Of course, for a lot of sites its not worth the time/effort to customize it.

Thank you very much, that is an excellent article, but I am a PHP novice person and I don`t want to learn right now (I am very busy with some projetcs) . I prefer to buy a script, if is resonable.:)

Thanks Xander, I searched on www.php.resourceindex.com and I found Captcha Creator - http://www.captchacreator.com , very easy to instal and ork nice. Anyway, I will still check a few other before I decide which one I will use on the long term!:)

Yes, good point of view, but I think the Captchas works good and reduce the number of spammers.:)

Buying a script is a definitely a good option. But just in case you don't find one that you like, you can easily set up a script using the article that i mentioned without learning PHP. I know that in the article the code is separated in sections, but if you want, i can put it together for you and give you instructions so you can use it in your current files.
