Imagecreatefromjpeg and similar functions do not work in PHP

I was looking for this, and the solutions provided in past issues are completely incomprehensible to me. Whenever I run functions like imagecreatefromjpeg , I get the following:

Fatal error: function call undefined imagecreatefromjpeg () ...

Im working on a new installation of PHP; my last install never had this problem. I do not understand what's going on.

You must enable the GD2 library.

Find your (correct) php.ini file

Find the line :; extension = php_gd2.dll and remove the semicolon in front.

The line should look like this:

 extension=php_gd2.dll

Then restart apache and you should be good to go.

On CentOS, RedHat, etc. use the command below. Remember to restart Apache. Because the PHP module must be loaded.

 yum -y install php-gd service httpd restart
