Preload next image in array?


Im wondering if someone could hint me in the correct direction to preload the next image in the array? Im clicking through an array of info, and the image is loaded from this computed property:

'questionImage': function () {
  let IMAGE_ROOT = location.protocol + "//" + + '/' 

  return this.activeQuestion.image ? (IMAGE_ROOT + this.activeQuestion.image) : false

And as it is, the image take a ms to load, and that it bothers that the image load for that ms. So how can I approach this issue?
