//食用方法
//把这个放在hexo的根目录
//先装cnpm  -->  npm install -g cnpm --registry=https://registry.npm.taobao.org
//然后 --> cnpm install -g gulp
//然后 --> cnpm install gulp gulp-htmlclean gulp-htmlmin gulp-clean-css gulp-uglify-es gulp-imagemin del gulp-minify-inline-json --save-dev
//修改img路径为你的source中实际的图片存储路径
//准备上传时 直接输入 gulp
