 With Webpack, using static assets like images and fonts works similarly to CSS.
 
 You can `import` an image right in a JavaScript. This tells Webpack to include that image in the bundle.
-The *result* of the import will be the final image filename in the compiled bundle.

 If you’d prefer to add and reference static assets in a more traditional way outside the module system, please let us know [in this issue](https://github.com/facebookincubator/create-react-app/issues/28), and we will add support for this.
