Php supports GDlibrary to install the plug-in NextGEN Gallery on wordpress to support photo albums. an error occurs after an image is uploaded.
You do not have the GD Library installed. This class requires the GD library to function properly. visit http://us2.php.net/manual/en/ref.image.php for more information

According to the online search, we learned that php needs to support the gb library for image generation,
So re-compile php and add it to configure? With-gd, error reported
Configure: error: libpng. (a | so) not found

Use? With-png-dir =/usr/lib, the error persists.
After yum install pnglib is used, re-compile php, or an error occurs.
Finally, try to use yum install pnglib-devel and re-compile php.

Php used pnglib-devel instead of pnglib.
