You can pass an object of components to render your custom content types such as images.

First, create an object for your PortableText custom components, and return your image component for the image type.

const myPortableTextComponents = {
  types: {
    image: ({ value }) => {
      return (
        <SanityImage {...value} />
      );
    },
  },
};

Second: Create your ImageComponent. I'm using the next-sanity-image plugin here to use the image with NextJS Image component.

import {useNextSanityImage} from 'next-sanity-image'
import Image from 'next/image';

const sanityConfig = sanityClient({
  projectId: process.env.NEXT_PUBLIC_SANITY_PROJECT_ID,
  dataset: process.env.NEXT_PUBLIC_SANITY_DATASET,
  useCdn: true
});

const SanityImage = ({ asset }) => {
  const imageProps = useNextSanityImage(sanityConfig, asset);

  if (!imageProps) return null;

  return (<Image 
    {...imageProps}
    layout='responsive'
    sizes='(max-width: 800px) 100vw, 800px'
  />);
}

Finally, pass the custom components object to your PortableText component via the components prop.

<PortableText
  value={body}
  components={myPortableTextComponents}
/>
