Best CAPTCHA Plugin?

I have WP v3.8.1, BP v1.9.2 and Keypic NO CAPTCHA Anti-Spam v1.4.1
I installed the plugin Keypic NO CAPTCHA Anti-Spam v1.4.1
I also registered myself on Keypic site and created the Form ID and I pasted that ID into the Keypic Configuration in my WP admin. And I selected ENABLE on all forms details. So I did everything according to instructions. But on my site on nowhere I can see the keypic images on any forms. So is there a shortcode pasting needed for form pages? If it is why never mentioned on Keypic site and readme file etc? If not needed, that admin configuration page is enough to make it work why is that not appearing anywhere on the site?
Could you please help out. Thanx.

Appears not all your website is done using WordPress

Activating the plugin for WordPress you can protect from spam forms included in WordPress, by the way, in your case you have to do something more.

I suppose you are using PHP in your web site, in this case, if you wish to protect your site against spammers you can download install and use the PHP Class that you can find here: https://github.com/keypic/keypic-php/blob/master/Keypic.php

Ask to your web master to use it, it’s very easy!

Thnx for quick reply
But I use fully WP, it has SweetDate theme, WP latest version and BuddyPress latest version. And I installed your plugin on my WP admin panel.

And after this info I gave you if you still insist that I have to use this: https://github.com/keypic/keypic-php/blob/master/Keypic.php
Pls tell me how to use it where to add this code could you please explain thanx.
