+Determines which image service is used by the adapter. The adapter will default to `cloudflare-binding` 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.
 - **`cloudflare-binding`:** Uses the [Cloudflare Images binding](https://developers.cloudflare.com/images/transform-images/bindings/) for image transformation. The binding is automatically provisioned when you deploy.
 - **`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. For pages rendered on demand, all `astro:assets` features are disabled.
+- **`compile`:** Uses a combination of internal dependencies to transform images locally at build time for prerendered routes. The noop `passthrough` option is configured for on-demand rendered pages.
 - **`custom`:** Always uses the image service configured in [Image Options](/en/reference/configuration-reference/#image-options). **This option will not check to see whether the configured image service works in Cloudflare's `workerd` runtime.**
 
+It is also possible to configure your image service as an object, setting both a build time and runtime service independently. Currently, `'compile'` is the only available build-time option. The supported runtime options are `'passthrough'` (default) and `'cloudflare-binding'`:

+### Changed: `imageService` default
+
+The default value of `imageService` has changed from `'compile'` to `'cloudflare-binding'` for an improved experience when working with images.
+
+The `cloudflare-binding` service uses the [Cloudflare Images binding](https://developers.cloudflare.com/images/transform-images/bindings/) to transform images at runtime, and the binding is automatically provisioned when you deploy.
+
+To revert to the previous behavior, where image transformation was only available on prerendered routes at build time, set `imageService: 'compile'` explicitly in your adapter config.
