Answer 1

php的语法变规范，变严谨了，所以以前不符合规范的代码就会给提示，这是好事，你要习惯。

Answer 2

ecshop的cls_image库中gd_version不是一个静态方法

http://de2.php.net/manual/en/language.oop5.static.php

Calling non-static methods statically generates an E_STRICT level warning.
用静态方式调用一个非静态方法会导致一个 E_STRICT 级别的错误。

http://us2.php.net/manual/en/errorfunc.constants.php

E_STRICT Enable to have PHP suggest changes to your code which will ensure the best interoperability and forward compatibility of your code. Since PHP 5 but not included in E_ALL until PHP 5.4.0
E_STRICT 启用 PHP 对代码的修改建议，以确保代码具有最佳的互操作性和向前兼容性。从 PHP 5.4 开始被默认启用。
