Webpack keine Bilder laden von CSS-Eigenschaft background-image

Ich habe keine Ahnung, was zu tun ist... ich bin mit Webpack mit CSS, style, sass und stylus-Lader. Hier ist mein webpack config... die Bilder nicht zeigen, wenn ich so etwas wie:

body
    background-image: url('bg.jpg')

Wenn ich Bild im HTML mit <img> tag-Sie arbeiten in der Regel...

Mein webpack config:

var path = require('path')

module.exports = {
  entry: {
    app: './src/main.js'
  },
  output: {
    path: path.resolve(__dirname, '../dist/static'),
    publicPath: '/static/',
    filename: '[name].js'
  },
  resolve: {
    extensions: ['', '.js', '.vue'],
    alias: {
      'src': path.resolve(__dirname, '../src')
    }
  },
  resolveLoader: {
    root: path.join(__dirname, 'node_modules')
  },
  module: {
    preLoaders: [
      {
        test: /\.vue$/,
        loader: 'eslint',
        exclude: /node_modules/
      },
      {
        test: /\.js$/,
        loader: 'eslint',
        exclude: /node_modules/
      }
    ],
    loaders: [
      {
        test: /\.vue$/,
        loader: 'vue'
      },

        loader: 'babel',
        exclude: /node_modules/
      },
      {
        test: /\.json$/,
        loader: 'json'
      },
      {

        loaders: ['style', 'css?sourceMap', 'sass?sourceMap']
      },
      {

        loader: 'url?prefix=font/&limit=10000&mimetype=application/font-woff'
      }, {

        ]
      }
    ]
  },
  eslint: {
    formatter: require('eslint-friendly-formatter')
  },
  vue: {
    loaders: {
