Explanation
Issue
#315requires alternative text enforcement, a meaningful error for missingalt, and no image output whenaltis missing. The current change adds only an opt-in type-level check.requireAltdefaults tofalse, andNuxtImg.vuestill renders<img>without a runtime guard. The documentation states that the option has no runtime effect. The change does not establish the required runtime behavior or automated tests for it.Resolution
Implement the runtime enforcement required by
#315in bothNuxtImgandNuxtPicture. Report a meaningful error and render no image output whenaltis omitted. Add automated tests for these cases. Update documentation examples with meaningfulalttext oralt=""where appropriate.

comma after the property alt: props.alt which is causing the lint failure;
update the normalizedAttrs object (the entry with alt: props.alt) to include a
trailing comma after that property so the object conforms to the project's
trailing-comma lint rule.

27-27: Consider adding descriptive alt text for consistency.Most samples use
alt: ''while some providers (strapi, storyblok, wagtail, directus) include meaningful descriptions. For a playground demonstrating image provider capabilities, descriptive alt text like"Bunny CDN sharpened image"or"Cloudinary cropped thumbnail"would improve documentation value and serve as better examples for users learning the module.Empty alt is valid per WCAG for decorative images, so this is entirely optional.
