If you have no access to your php.ini file you have to ask your webhosting company to enable the GD2 support for you. Otherwise you have to edit the php.ini file on your system and remove the semicolon in the following line:
Linux/Unix/MacOS:
extension=php_gd2.so
Windows
extension=php_gd2.dll
After saving your edited php.ini file you have to restart your webserver and GD2 support is enabled.
On a Gentoo system, make sure that the "gd" USE flag is used when PHP is built.
