title: 'Invalid `images` config'
---

## Why This Error Occurred

In your `next.config.js` file, you provided an invalid config for the `images` field.

## Possible Ways to Fix It

Make sure your `images` field follows the allowed config shape and values:

```js filename="next.config.js"
module.exports = {
  images: {
    // limit of 25 deviceSizes values
    deviceSizes: [640, 750, 828, 1080, 1200, 1920, 2048, 3840],
    // limit of 25 imageSizes values
    imageSizes: [16, 32, 48, 64, 96, 128, 256, 384],
    // limit of 50 domains values (deprecated)
    domains: [],
    // path prefix for Image Optimization API, useful with `loader`
    path: '/_next/image',
    // loader can be 'default', 'imgix', 'cloudinary', 'akamai', or 'custom'
    loader: 'default',
    // file with `export default function loader({src, width, quality})`
    loaderFile: '',
    // disable static imports for image files
    disableStaticImages: false,
    // minimumCacheTTL is in seconds, must be integer 0 or more
    minimumCacheTTL: 60,
    // ordered list of acceptable optimized image formats (mime types)
    formats: ['image/webp'],
    // enable dangerous use of SVG images
    dangerouslyAllowSVG: false,
    // set the Content-Security-Policy header
    contentSecurityPolicy: "default-src 'self'; script-src 'none'; sandbox;",
    // sets the Content-Disposition header ('inline' or 'attachment')
    contentDispositionType: 'attachment',
    // limit of 50 objects
    remotePatterns: [],
    // when true, every image will be unoptimized
    unoptimized: false,
  },
}
```
