Closes #850.

Problem

In local development, @nuxt/image defaults to the ipx provider when image.provider is not configured.

When your images are served by a Nuxt route (for example /images/** via blob.serve()), IPX generates /_ipx/... URLs and then tries to read the source from the filesystem, not by requesting your /images/** route. This leads to IPX_FILE_NOT_FOUND.

Minimal repro (Nuxt 4.3.1, @nuxt/[email protected], @nuxthub/[email protected]):

• Blob route returns 200:
  • curl -i http://127.0.0.1:3000/images/photo.png
• NuxtImg + default IPX fails:
  • curl -i 'http://127.0.0.1:3000/_ipx/w_300&q_80/images/photo.png' -> 404 IPX_FILE_NOT_FOUND
• Setting image: { provider: 'none' } makes <NuxtImg> pass-through and use /images/... URLs -> works.

Local evidence captured:

• baseline (IPX): /tmp/nuxthub-850-baseline.png
• fixed (none): /tmp/nuxthub-850-fixed.png

Changes

• Add an explicit /images/** blob.serve() route snippet to the Nuxt Image section and link to the full "Serve a blob" docs.
• Recommend image: { provider: 'none' } for development/default config.
• Keep platform providers (Cloudflare/Vercel) in $production only.
• Remove cloudflare.baseURL: '/images' from the example.
• Fix the "Serve a blob" snippet to include the missing imports/param handling.
