One of the main reasons to use webpack would be to decrease the number of requests to a CDN or web server to load images, but usually it’s not worth the overhead. With webpack the images are encoded in base64 strings and then inserted directly into the code where they are then rendered.

For your use case I would recommend that you just turn on the CDN option with your Spaces folder:
Enable CDN for Spaces

And you should be good to go without having to worry about webpack.

With the CDN your images will be cached at the edge and will load quickly. Beyond that it’s usually overkill unless you are dealing with millions of requests.

I know this is old question. But in the past, I have placed the smaller images into a single image file then used javascript / CSS to move around in that image and only display the image I want. This seriously improved performance of my applications. In a single http request, all my images were pulled at once.
