The Captcha image is too small

The ChronoForms Captcha setting defaults to quite a small type size. Her's how to use an image with a larger and clearer font:

If you are using the Easy Wizard set "Use True Type Fonts" to 'Yes' on the Captcha tab.

If you are using the normal/advanced Form Wizard open the Load Captcha action and set "True Type Font Support" to "With Fonts Support".
