主题：【借花献佛】老外的眼睛看上海-偶老板拍的照片 -- 就爱在家捣鼓

It's better tell your boss directly that you like his pictures very much especially above two. Then ask him straightforwardly, "can I keep them and share with my friends?" It is very very easy. And your boss will be happy that someone likes his photos since that will make him feel like a master.
