PHP5.4会报如下错误Non-static method cls_image::gd_version() should not be called statically in解决方法：1）将function gd_version()改成static function gd_version()即可。2）或者将install/includes/lib_installer.php中

//$tag_sel = array_shift(explode(' ', $tag));把上面的改为如下两行即可：            $tag_arr=explode('',$tag);            $tag_sel = array_shift($tag_arr);
