No img element

Prevent usage of <img> element to prevent layout shift and favor optimized images.

Why This Error Occurred

An <img> element was used to display an image.

Possible Ways to Fix It

Use next/image to improve performance with automatic Image Optimization.

Note: If deploying to a managed hosting provider, remember to check pricing since optimized images might be charged differently that the original images. If self-hosting, remember to install sharp and check if your server has enough storage to cache the optimized images.

import Image from 'next/image'

function Home() {
  return (
    <Image
      src="https://example.com/hero.jpg"
      alt="Landscape picture"
      width={800}
      height={500}
    />
  )
}

export default Home

If you would like to use next/image features such as blur-up placeholders but disable Image Optimization, you can do so using unoptimized.

Or, use a <picture> element with the nested <img> element:

function Home() {
  return (
    <picture>
      <source srcSet="https://example.com/hero.avif" type="image/avif" />
      <source srcSet="https://example.com/hero.webp" type="image/webp" />
      <img
        src="https://example.com/hero.jpg"
        alt="Landscape picture"
        width={800}
        height={500}
      />
    </picture>
  )
}
