Use python to backup blog image bed images

illustrate

Recently, in the process of writing markdown documents, it is often necessary to insert some pictures. Because the server space for hosting the blog is limited, upload pictures to the picture bed and then insert them into markdown. Sometimes pictures from the Internet are inserted, and these pictures may become invalid at any time. My blog website shows an image error.
So it took a while to use python to match the image link in markdown, and then download the image and save it to a local folder img. In this way, I don't have to worry about the image being invalid. When I find a stable image bed, I can Feel free to upload and update these pictures at any time, it's beautiful~~~
