以lazyload插件为例，需要替换src标签为data-original，如果还想使用默认的markdown格式，势必要对img的渲染过程进行重载。
首先修改默认的markdown插件，node_modules/hexo-renderer-marked/lib/renderer.js

var tmpHtml = markedRenderer.complete.call(this, html);
if (!tmpHtml) {
html = tmpHtml;
}
}
return html;
};

init: function() {
// console.log("hexo.markedRenderer init!");
// Called before rendering
},
complete: function(html) {
// console.log("hexo.markedRenderer complete!");
// Called after rendered
// Deal with html here ...
return html;
},
image: function(href, title, alt) {
// Default method can be accessed via:
// this._super.heading(text, level)
var orimg = '<img data-original="' + href;
if (title) orimg += '" title="' + title;
if (alt) orimg += '" alt="' + alt;
return orimg + '">';
}
};

完成。
