Requirements
If you have the GD library (available at » http://www.libgd.org/) you will also be able to create and manipulate images.
The format of images you are able to manipulate depend on the version of GD you install, and any other libraries GD might need to access those image formats.
Note: libgd-2.1.0 or higher is required. Alternatively, use the bundled GD library that ships with PHP.
You may wish to enhance GD to handle more image formats.
| Image format | Library to download | Notes |
|---|---|---|

When building the jpeg library (prior to building PHP) you
must use the --enable-shared
option in the configure step. If you do not, you will receive
an error saying libjpeg.(a|so) not found
when you get to the configure step of building PHP.

You may wish to enhance GD to deal with different fonts. The » FreeType 2 library is supported.
