Which entry in phpinfo() tells about the GD library?

Question

I want to make a captcha programming inside my form. I googled about "php captcha" and I found that the GD library should be installed. I made a phpinfo() and I cannot see what is the keyword to recognize the GD library ; the version of my PHP is 5.2.1

So what is the entry text of the GD library in phpinfo() , and how to enable the GD library ?

Answer 1

Go for gd section and check (if you have enabled you found a new section with named gd)

GD Support enabled
