This GatsbyJS plugin is creating a multi-layered react component with changing background images on mouse or touch moves. The images are in full width and cover the whole wrapper element. It's showen one image at a time. While moving the mouse in any direction the images are beeing iterated and exchanged. On touch devices only the x-axis is beeing tracked for iterating the images.

When do I use this plugin?

This plugin is perfect to have an interactive first impression of your website. The images are in the background so you can easily put content in front of them. It is a kind of interactice slide show.

Examples of usage

import React from "react"
import { useStaticQuery, graphql } from "gatsby"
import ImageMap from "gatsby-plugin-react-image-map" // import the image-map plugin

const ImageMapContainer = () => {
  /**
   * Query the images you'd like to be visible inside the image map.
   * In this case the regular expression is looking for images inside
   * the `image-map` folder inside your `src`
   */
  const data = useStaticQuery(graphql`
    query ImageMapQuery {
      allFile(filter: {sourceInstanceName: {eq: "image-map"}}) {
        nodes {
          childImageSharp {
            fluid {
              ...GatsbyImageSharpFluid_noBase64
            }
          }
          relativePath
        }
      }
    }
  `)
   
  return (
    <ImageMap nodes={data.allFile.nodes}/>
  )
}

export default ImageMapContainer
