title: Webpack not loading images from CSS background-image property
body: <p>I have no clue what to do... I am using Webpack with CSS, style, sass and stylus loaders. Here is my webpack config... Images do not show up when I use something like:</p>
  
  <pre><code>body
      background-image: url('bg.jpg')
  </code></pre>
  
  <p>If I include image inside HTML with <code>&lt;img&gt;</code> tag they work normally...</p>
  
  <p>My webpack config:</p>
  
  <pre><code>var path = require('path')
  
  module.exports = {
