Image optimizer disabled (unoptimized: true)
Part of the Caching & cost check · fix arrives as a guide
What it is
Next.js image optimisation is disabled with unoptimized: true.
Why it matters
Full-size originals are then served on every request in their original format. It is a bandwidth cost on your side and a slow page on the user's, particularly on mobile connections.
How to fix it
Remove unoptimized: true and let the optimiser resize and re-encode. If it was disabled because of an export constraint, use a loader that points at an optimisation service instead.
