gitee轉之前：
https://gitee.com/nmydt/picture-bed/blob/master/img/97a8eacc9ea407bb.jpg
轉之后
https://gitee.com/nmydt/picture-bed/raw/master/img/97a8eacc9ea407bb.jpg
即將blob換成raw
github轉之前：
https://github.com/yourusername/test/blob/master/img/3.jpg
轉之后
https://github.com/yourusername/test/raw/master/img/3.jpg
即將blob換成raw
其實上方鏈接最終跳轉到
https://raw.githubusercontent.com/yourusername/test/master/img/3.jpg
即也可以改成
github.com換成raw.githubusercontent.com，刪去blob即為最終鏈接
