Features:

• User Friendly: The captcha uses easily understandable images instead of hard to read texts to complete the captcha.
• Server-side Validation: Any validation done by the captcha will be performed on the server-side instead of the client-side.
• Self-Hosted: Because IconCaptcha is a self-hosted plugin, you are not relying on any third party.
• No Data Sharing: Unlike captchas such as Google ReCaptcha, no user data will be stored or sold to third parties.
• jQuery Support: IconCaptcha is written in plain JavaScript, but hooks into jQuery to allow you to integrate it in your jQuery code.
• Modern Design: The look and feel of IconCaptcha fits every modern website design.
• Events: Events are triggered at various points in the code, allowing you to hook into them and execute custom code if necessary.
• Themes: Change the design of the captcha without having to ever touch a stylesheet.
• SASS: The project contains a SASS file, allowing you to easily style and compile the stylesheet.
• IE 10+ Support: IconCaptcha has been tested in Internet Explorer 10 & 11 and is functional in both versions.
