PW3 - Securimage Captcha Integration

[ridgedale]

I was wondering if anyone has successfully integrated Securimage with Processwire 3.

I've tried the suggested fixes posted here, but I haven't managed to get the captcha image to display. This might be because the instructions relate to Processwire version 2.x where I am working with version 3.

Any ideas/steps what to do would be appreciated.
