Next.js Image Component Optimization Error

Using next/image causes errors. Image won't load or throws configuration error. Image optimization fails.

Error about missing width/height, or optimization service unavailable.

Error Messages You Might See

Error: Image with src should have width and height Error: Image Optimization API error Image domain not configured Unoptimized image with static size
Error: Image with src should have width and heightError: Image Optimization API errorImage domain not configuredUnoptimized image with static size

Common Causes

  1. Width/height not provided on Image component (required for static imports)
  2. External image domain not whitelisted in next.config.js
  3. Image format not supported by Next.js optimization
  4. Invalid src prop (relative path instead of absolute)
  5. Image optimization disabled but image props incorrect

How to Fix It

Always provide width and height: ...

For external images, add to next.config.js: { images: { remotePatterns: [{ hostname: 'example.com' }] } }

Use static import when possible: import img from '@/public/img.jpg'; ...

Ensure image file exists and is valid format (jpg, png, webp, gif)

Day job: I'm the sole backend developer at merketing company where I own and maintain 11 PHP/Symfony microservices on AWS (ECS Fargate, RDS, S3, CloudFront), handle the full CI/CD pipeline (Bitbucket Pipelines, Docker), and manage monitoring with Sentry and CloudWatch. These services handle high request volumes in production every month. What I bring to AI-built apps: - I audit and fix security issues (OWASP methodology), performance bottlenecks, and architectural problems in codebases generated by Cursor, Claude Code, Lovable, Bolt, and v0 - I refactor AI-generated prototypes into production-grade applications with proper error handling, testing, and clean architecture (SOLID, DDD, hexagonal architecture) - I set up the infrastructure AI tools don't touch: AWS hosting, CI/CD pipelines, automated deployments, database optimization, monitoring, and alerting - I integrate external services: payment providers, email systems, partner APIs, SSO/auth Tech stack: PHP 8.x, Symfony, React, Next.js, PostgreSQL, MySQL, Docker, AWS (ECS, RDS, S3, SQS/SNS, CloudFront), Terraform, Supabase. I also use AI tools daily (Claude Code, Cursor) in my own workflow, so I understand both the strengths and the gaps in AI-generated code. Based in Poland (CET timezone).

Frequently Asked Questions

When can I skip width/height?

Only with layout=fill (position: absolute parent) or static import with Babel plugin

How do I whitelist external image domains?

In next.config.js: images: { remotePatterns: [{ hostname: 'cdn.example.com', protocol: 'https' }] }

Is Image component always better than img tag?

Yes for web. Image automatically optimizes, lazy loads, handles responsive sizes. Always use next/image
