Why I like to use blog garden, because a lot of style can design your own! The next two steps can put your head into the blog sidebar.
1. Go to your blog park to find the "Settings" ---> "blog sidebar" and then paste the following code into it
2. <img src = "https://images.cnblogs.com/cnblogs_com/youliang-null/1657775/o_200303133312 snake .jpg" alt = "blog owners of small bright picture" class = "img_avatar" width = "200px "style =" border-radius: 50% ">
Note: src is the image path, 200px is used to adjust the image size, 50% is used to adjust the degree of fillet.
If you do not find the page image path, you can now upload pictures to an album, open the picture, right from the album, and then check the elements copied image path.
