From error above, can anyone explain me the error and how to solve it?

You need to enable GD extension in your PHP installation. Try that through your server's cPanel or ask your host.

To be honest I am still not understand how to download GD extension in my PHP. Can someone guide me this?

You need to have root access to a server to install GD.
Could you please share how you solved it?

Sure. Since I use XAMPP, then I opened my XAMPP and click Config on Apache. find the name "PHP (php.ini)" and click it. Scroll down until you find ";Extension=GD". as it seems here, semicolon at the beginning of sentence is working as disable function. So take out the semicolon from that sentence and everything is already settled.
