Ecshop：cls_image::gd_version()和不支持JPEG

在安装Ecshop的时候，遇到两个问题：

Strict Standards: Non-static method cls_image::gd_version() should not be called statically in /var/www/html/gotosth/install/includes/lib_installer.php on line 31
Strict Standards: Non-static method cls_image::gd_version() should not be called statically in /var/www/html/gotosth/install/includes/lib_installer.php on line 31

解决：
找到install/includes/lib_installer.php中的第31行 return cls_image::gd_version();
然后在找到include/cls_image.php中的678行，发现gd_version()方法未声明静态static，所以会出错。这时候只要： 　　

1）将function gd_version()改成static function gd_version()即可。
2）或者将install/includes/lib_installer.php中的第31行return cls_image::gd_version();改成：
$p = new cls_image();
return $p->gd_version();
