GD isn't installed, either recompile PHP or load the module.
This depends on your CentOS/RedHat version so it's best to contact your hosting provider.
Because your current PHP compile command is
Code:
./configure --with-apxs=/usr/local/apache/bin/apxs --prefix=/usr/local --with-xml --enable-bcmath --enable-calendar --enable-ftp --enable-magic-quotes --with-mysqli --with-mysql=/usr --enable-discard-path --with-pear --enable-sockets --enable-track-vars --with-zlib
And for full control it should look more like
Code:
./configure --with-apxs=/usr/local/apache/bin/apxs --prefix=/usr/local --with-xml --with-mm --enable-bcmath --enable-calendar --enable-exif --enable-ftp --with-gd --with-jpeg-dir=/usr/local --with-png-dir=/usr --with-xpm-dir=/usr/X11R6 --with-gettext --enable-memory-limit --with-mm --with-mysqli --with-mysql=/usr --with-openssl --enable-discard-path --with-pgsql=/usr --enable-sockets --enable-track-vars --with-ttf --with-freetype-dir=/usr --enable-gd-native-ttf --with-zip --with-zlib
