Using Slider CAPTCHA, you can replace or add a CAPTCHA to your WordPress forms. By default, Slider CAPTCHA will add a CAPTCHA to your templates’ comment form. You can also add sliders to the Registration form, Password Recovery form and the Login form.
Besides, you can use the <code>slider_captcha()</code> function to insert a Slider CAPTCHA wherever you want, and fully costumize it.
With our brand new Settings page, you can now fully custumize every Slider on your WordPress installation and live preview the result. In the upcoming version, you will be able to create your own slider. At the moment, if you want to create your own custom slider you should use the <code>slider_captcha()</code>. Check the FAQ for more info.
