How should I use Gatsby.js to generate both the thumbnails and full-size images

Question

What should I do if I need both a thumbnail(ie low resolution version) of a picture and the full size version.

I have a medium style image zoom component( https://codesandbox.io/s/cool-butterfly-w78l5 ) and I want that component to show the thumbnails and only when it is being clicked on and it gets zoomed out it shows the full-size picture by specifying different url to src and enlargedSrc .

this is how I query all my images files

const ImageSupplier = () => {
  const { allFile } = useStaticQuery(graphql`
    query {
      allFile(
        filter: {
          extension: { regex: "/(jpg)|(jpeg)|(png)/" }
          sourceInstanceName: { eq: "imageFolder" }
        }
      ) {
        edges {
          node {
            childImageSharp {
              fluid(
                maxWidth: 800
                quality: 95 
              ) {
                originalName
                ...GatsbyImageSharpFluid_withWebp
              }
            }
          }
        }
      }
    }
  `);

But it only gives me the full-size image with fluid.src , it also comes with a srcSet but I have no idea how to use srcSet to achieve what I want.

Answer 1

1. You should use Gatsby-Image .
2. You query for the images twice. You use fixed with a low resolution for thumbnails. You keep using your current implementation the full-size images.
