  To enable GD-support configure PHP
  <option role="configure">--with-gd[=DIR]</option>, where DIR is the GD base
  install directory. To use the recommended bundled version of the GD library
  (which was first bundled in PHP 4.3.0), use the configure option 
  <option role="configure">--with-gd</option>.
  GD library requires <productname>libpng</productname> and
  <productname>libjpeg</productname> to compile.

 <para>
  In Windows, you'll include the GD2 DLL <filename>php_gd2.dll</filename> as
  an extension in &php.ini;. The GD1 DLL <filename>php_gd.dll</filename> was
  removed in PHP 4.3.2. Also note that the preferred truecolor image
  functions, such as <function>imagecreatetruecolor</function>, require GD2.

  Enhance the capabilities of GD to handle more image formats by specifying
  the <literal>--with-XXXX</literal> configure switch to your PHP configure
  line.

       to your configure line.
