Rails + React + Webpack loading an image - ruby-on-rails

Question

I'm using rails + webpack to compile a bundle.js file into the rails asset pipeline. I placed an image inside /app/assets/images called "main.png". How can I access this image inside a React component that's being bundled?
I'm using shakacode's react on rails gem. https://github.com/shakacode/react_on_rails
I then tried using webpack to process the image which it did successfully and placed the image next to the bundle.js file. I still get a 404 on the image.
I know I'm close, just have the publicPath wrong for the rails asset. This current setup gives a localhost:3000/webpack/main.png which isn't working with rails.
This is my webpack file:
const webpack = require('webpack');
const path = require('path');
const devBuild = process.env.NODE_ENV !== 'production';
const nodeEnv = devBuild ? 'development' : 'production';
config = {
entry: [
'es5-shim/es5-shim',
'es5-shim/es5-sham',
'babel-polyfill',
'./app/Register.js',
],
output: {
filename: 'webpack-bundle.js',
path: '../app/assets/webpack',
publicPath: '/webpack/'
},
resolve: {
extensions: ['', '.js', '.jsx'],
alias: {
react: path.resolve('./node_modules/react'),
'react-dom': path.resolve('./node_modules/react-dom'),
},
},
plugins: [
new webpack.DefinePlugin({
'process.env': {
NODE_ENV: JSON.stringify(nodeEnv),
},
}),
],
module: {
loaders: [
{
test: require.resolve('react'),
loader: 'imports?shim=es5-shim/es5-shim&sham=es5-shim/es5-sham',
},
{
test: /\.jsx?$/, loader: 'babel-loader',
exclude: /node_modules/,
},
{
test: /\.(png|svg)$/i,
loaders: [
'file?hash=sha512&digest=hex&name=[hash].[ext]',
'image-webpack?bypassOnDebug&interlaced=false'
]
}
],
},
};
module.exports = config;
if (devBuild) {
console.log('Webpack dev build for Rails'); // eslint-disable-line no-console
module.exports.devtool = 'eval-source-map';
} else {
config.plugins.push(
new webpack.optimize.DedupePlugin()
);
console.log('Webpack production build for Rails'); // eslint-disable-line no-console
}

After defining a loader properly, you can load your image with a require function, for example! For example, add near your imports:
const myImg = require('./assets/methods.png');
Then, in your component's render method:
<img src={myImg} />
That should work...
