When I add the image shortcode, can not show image.

When I add an image shortcode to template index.njk, just like {% image "./src/images/hero.jpg", "Hero image" %} it always show [object Promise].

I changed the shortcode to be for synchronous usage, as opposed to asynchronous usage, as explained in the Eleventy Image documentation, and that seems to have resolved it. It is now in my repo for this starter (as well as the three others which had the previous code), or you can replace the shortcode in your existing .eleventy.js file with the code shown below. Thanks very much for reporting this, and I apologize for the problem!

  // --- START, eleventy-img
  function imageShortcode(src, alt, sizes="(min-width: 1024px) 100vw, 50vw") {
    console.log(`Generating image(s) from:  ${src}`)
    let options = {
      widths: [600, 900, 1500],
      formats: ["webp", "jpeg"],
      urlPath: "/images/",
      outputDir: "./_site/images/",
      filenameFormat: function (id, src, width, format, options) {
        const extension = path.extname(src)
        const name = path.basename(src, extension)
        return `${name}-${width}w.${format}`
      }
    }

    // generate images
    Image(src, options)

    let imageAttributes = {
      alt,
      sizes,
      loading: "lazy",
      decoding: "async",
    }
    // get metadata
    metadata = Image.statsSync(src, options)
    return Image.generateHTML(metadata, imageAttributes)
  }
  eleventyConfig.addShortcode("image", imageShortcode)
  // --- END, eleventy-img
