由于Gitee作为图床的仓库被禁止开源，导致图片无法访问，所以转用Github作为图床。
下载图片文件并上传
（1）将作为图床的Gitee仓库下载到本地
（2）新建一个Github仓库作为图床，具体创建过程可参考CDN加速GitHub搭配PicGo自建图床
（3）执行如下步骤将下载的文件中的所有图片上传到Github

| 1. 克隆：git clone git@github.com:username/cdnPicture.git
2. 复制你下载的图片到cdnPicture中
3. 添加到暂存区：git add .
4. 把暂存区的所有更改提交到了本地仓库中：git commit -m"init all imgs"
5. 提交main分支到github上：git push origin main

CDN加速GitHub搭配PicGo自建图床
详细步骤不多说了，具体参考CDN加速GitHub搭配PicGo自建图床。
这里要提一句，使用https://fastly.jsdelivr.net/,和使用https://cdn.jsdelivr.net/都可，原来的图床图片地址为：https://raw.githubusercontent.com/wxler/cdnPicture/main/imgs/20220605212813.png。
替换后为：
批量替换文件中的图片url
如果只替换一个，那么只有写一个from和一个to变量即可。
注意：为了防止出错，替换前记得备份
