Easily switched out for a url loader this loader can be injected directly into an img src tag
If your looking for a loader that simple encodes as base64 try base64-loader
npm install base64-image-loader
var fileAsBase64Src = require("base64-image!./file.png");
document.write('<img src="' + fileAsBase64Src + '" />';
