Get image width and height with JavaScript

function imageSize (image) {
  return new Promise((resolve, reject) => {
    try {
      const fileReader = new FileReader()

      fileReader.onload = () => {
        const img = new Image()

        img.onload = () => {
          resolve({ width: img.width, height: img.height })
        }

        img.src = fileReader.result
      }

      fileReader.readAsDataURL(image)
    } catch (e) {
      reject(e)
    }
  })
}

please put this example in context(in an html page). showing <input..multiple..image only etc. that would be very helpful, thank you

Thanks a lot!

I always receive that image is undefined when I add readAsDataUrl

Works not in chrome with
`

<svg width="100%" height="100%" viewBox="0 0 4963 3509" ...`
SVGs
