Gatsby has introduced support for Image CDN, which can save build times by handling image processing at runtime, but only works for certain CMS integrations. A new experimental Gatsby Runner has been developed to achieve the same results for all images in Gatsby, including local images, without requiring any changes to your Gatsby code. The Gatsby Runner cuts build times by 84% and total deploy time by 62%, even more for sites with many images. It processes images at runtime, using On-demand Builders, and includes the jobs JSON files inside the builder function bundle. The plugin is still experimental but can be installed as a separate build plugin to save build times.
