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.
The *result* of the import is the image filename from the build output folder.
Here is an example:

Webpack will thefind relative module references in CSS (they start with `./`) and replace them with the final paths in the compiled bundle. If you make a typo or accidentally delete an important file, you will see a compilation error, just like when you import a non-existent JavaScript module.
Webpack finds all relative module references in CSS (they start with `./`) and replaces them with the final paths from the compiled bundle.
The filenames are generated by Webpack from content hashes. If the file content changes in the future, Webpack will give it a different name in production so you don’t need to worry about long-term caching of assets.

Please be advised that this is also a custom feature of Webpack.
**It is not required for React** but many people enjoy it (and React Native uses a similar mechanism for images).

However it may not be portable to some other environments (for example, Node.js and Browserify).
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.
