Get the Original Height/Width Pixel Size of an Image by its URL

// <https://cdn.sanity.io/images/><project>/<dataset>/<uuid>-442x255.png?params=whatever

  const [originalWidth, originalHeight] = new URL(url).pathname
    .split('/')
    .filter((p) => p)
    .pop()
    .split('.')
    .slice(0, 1)
    .join('')
    .split('-')
    .pop()
    .split('x')
    .map((px) => parseInt(px))

// Returns 442, 255
