Or do they have two versions of the image at the server-side, a smaller one with low-quality which

I'm using url-loader with the following config for webpack { test: /\.(png|jpg|)$/, loader: 'url-loader?limit=200000' } Within the component I know I can add require(image_path) for a specific image at the top of the file before I create the component but I want make the component generic and have it take a property with the
