Getting "imagepng function not detected in php" Error

  • Posted May 12, 2014

I have used ‘Fast secure contact from’ plugin on my blog.

When someone is trying to fill the form it is displaying…

  1. error si-captcha.php plugin says imagepng function not detected in php
  2. error si-captcha.php plugin says gd image support function not detected in php

How to install these functions in php?
