SecurImage Captcha Plugin

Protect your Joomla Forms with SecurImage captcha plugin

This Captcha plugin works with any Joomla extension capable of using the Joomla core captcha plugin system. It uses the Securimage PHP CAPTCHA1 script for generating complex images and CAPTCHA codes (including math problems) to protect forms from spam and abuse. It can be easily added into existing forms on your Joomla website to provide protection from spam bots. It can run on almost all web servers as long as you have PHP installed, and GD support within PHP. SecurImage does everything from generating the CAPTCHA images to validating the typed code. Audible codes can be streamed to the browser with Flash for the vision impaired.

It's compliant with GDPR (General Data Protection Regulation). The plugin does not store any user information and it doesn't use cookies.

Usage

We've tried to make it very simple to use Captcha.

  1. Select Extensions → Plug-in Manager from the drop-down menu of the Joomla! Administrator Panel.
  2. Edit the Plug-In "Captcha - SecurImage"
    • Set Status to "Published"
    • Change the settings accordingly to your needs. Below is a screenshot of all the available settings;
  3. Go to System → Global Configuration, and select the "Site" tab.
    Choose "SecurImage" in your "Default Captcha" field.
    Click Save & Close.
  4. Depending on the form you need to protect with SecurImage you might have to go to the component Options and enable captcha there;

IMPORTANT: If you are using Akeeba Admin Tools you must access the ".htaccess maker" and add the folder "plugins/captcha/securimage/lib" into "Allow direct access, including .php files, to these directories" in order for the images to generate and be visible.
