-Adds support for using a custom tag (component) for optimized images
-
-Starting from this version, when a tag called `image` is used, its `src` attribute will automatically be resolved if it's a local image. Astro will pass the result `ImageMetadata` object to the underlying component as the `src` prop. For non-local images (i.e. images using URLs or absolute paths), Astro will continue to pass the `src` as a string.
-
-```ts
-// markdoc.config.mjs
-import { component, defineMarkdocConfig, nodes } from '@astrojs/markdoc/config';
-
-export default defineMarkdocConfig({
-	tags: {
-		image: {
-			attributes: nodes.image.attributes,
-			render: component('./src/components/MarkdocImage.astro'),
-		},
-	},
-});
-```
-```astro
----
-// src/components/MarkdocImage.astro
-import { Image } from "astro:assets";
-
-interface Props {
-  src: ImageMetadata | string;
-  alt: string;
-  width: number;
-  height: number;
-}
-
-const { src, alt, width, height } = Astro.props;
