Describe the Bug

As per the docs:

You can optionally state the image file type to be used. The default file format used is webp.

However, given this code:

---
import spain from '~/assets/spain.jpeg';
import { Image } from 'astro:assets';
---
<Image src={spain} width={600} alt="Some Text" />

I always end up receiving jpg not webp so I'm slightly confused.

As a side note it doesn't matter if I have squoosh explicitly specified in astro.config.mjs or not.

This was fixed in #6555. Just hasn't been released yet, we'll do a release shortly. Sorry for the inconvenience!

Fwiw, the file format is correct, it's just the file extension that's wrong

Thanks for the update. I checked the headers and the images also come back as image/jpeg - not sure if that's driven by the extension or not by the browser though.
