Strict Standards: Non-static method cls_image::gd_version() should not be called statically in C:\ECShop_V2.7.3_UTF8_rel\install\includes\lib_installer.php on line 31
定位文件到lib_installer.php的31行后，发现这个代码：
include_once(ROOT_PATH . 'includes/cls_image.php');
return cls_image::gd_version();
所以去root下，我这里也就是:ECShop_V2.7.3_UTF8_rel这个目录下找includes 下的cls_image.php
通过查找，在第678行找到这个函数的定义，修改为：
static function gd_version()
即可！
