hexo中使用hexo-asset-image插件来加载本地图片

在使用hexo时,在md文件里加载图片一般都会用到网络上的图片,但是如果有些图片不允许使用,怎么办?当然可以用七牛云这种图床网站,如果想使用本地的图片怎么办呢?那就用到了hexo-asset-image这个插件,但是这个插件写的很早,与现在新版本的hexo不兼容,于是乎就有一些大牛进行了修改,这里贴出这位大牛的github地址,兼容新版本hexo的hexo-asset-image插件

使用方法就是替换掉npm安装的hexo-asset-image插件中的文件,代码如下

Make sure post_asset_folder: true in your _config.yml.
Just use ![logo](logo.jpg) to insert logo.jpg.
