 Determines which image service is used by the adapter. The adapter will default to `passthrough` mode when an incompatible image service is configured. Otherwise, it will use the globally configured image service:
 
 * **`cloudflare`:** Uses the [Cloudflare Image Resizing](https://developers.cloudflare.com/images/image-resizing/) service.
 * **`passthrough`:** Uses the existing [`noop`](/en/guides/images/#configure-no-op-passthrough-service) service.
+* **`compile`:** Uses Astro's default service (sharp) to optimize images during build.

+})

+:::caution
+While the option `compile`, allows you to optimize Images using sharp, during build, it disables any support for image optimization during SSR. You need to make sure that you don't use any Image features in SSR routes (e.g. `<Image />`, `<Picture />`, `getImage()`.
+That means all images to be optimized need to be placed on routes which are pre-rendered.
