No img element
Prevent usage of
<img>
element due to slower LCP and higher bandwidth.
Why This Error Occurred
An <img>
element was used to display an image instead of <Image />
from next/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 provider pricing since optimized images might be charged differently than the original images.
Common image optimization platform pricing:
Note: If self-hosting, remember to install
sharp
and check if your server has enough storage to cache the optimized images.
pages/index.js
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:
pages/index.js
import Image from 'next/image' const UnoptimizedImage = (props) => { return <Image {...props} unoptimized /> }
- You can also use the
<picture>
element with the nested<img>
element:
pages/index.js
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> ) }
- You can use a custom image loader to optimize images. Set loaderFile to the path of your custom loader.
next.config.js
module.exports = { images: { loader: 'custom', loaderFile: './my/image/loader.js', }, }
