By default, the Signup-Free of DaloRADIUS is designed to spit a captcha code as shown above.

To fix it, how about we use the snippet below, which offers the opportunity to specify the font size, thus we can blow the size to as much big as we want.

You’ll include this snippet within the php-captcha.php file from here. You’ll know what to take out:

I hope the above helps you providing a better captcha image for users to look at and solve!
