给wordpress安图像插件handlines

却
FATAL: Your PHP installation does not support the ImageCreateTrueColor() or the ImageCreate() function.
Unforunately, there is not much this plugin can do without that. Talk to your hosting administrator about upgrading to a version that supports image manipulation and try again with the plugin.

请教高手怎么解决?

先前我用appserv安装apache+php+mysql+phpmyadmin没有以上问题.
后来手工安装配置apache+php+mysql+phpmyadmin才出现上列状况.
