Describe the Bug

Use standard Markdown![alt](src) syntax in your .md files. This syntax works with Astro’s Image Service API to optimize your local images and authorized remote images.
https://docs.astro.build/en/guides/images/#images-in-markdown-files

Although the documentation says it will optimise "your local images and authorized remote images", it doesn't actually optimise authorized remote images.

What's the expected result?

Authorized remote images will be optimized in Markdown.

Thank you for bringing this up currently remote images in Markdown are not processed by Astro’s Image Service. The docs here are misleading, sorry about that.

Yeah, processing remote images in Markdown / MDX / Markdoc using the native syntax is currently not supported. It has never been since the feature has been introduced, so the docs is wrong on the matter
