 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), but only on pre-rendered routes at build time. During SSR for pages rendered on-demand, all `astro:assets` features are disabled.
