How to start autoplay just after loading the first image of the first slide?

My Swiper is working really great with these setting:

var mySwiper = new Swiper ('.swiper-container', {

                pagination: '.swiper-pagination',
                paginationClickable: true,

                nextButton: '.swiper-button-next',
                prevButton: '.swiper-button-prev',

                // AutoPlay
                autoplay: 10000,
                speed: 1500,
                watchSlidesProgress: true,
                watchVisibility: true,

                // Loop
                loop: true,
                loopAdditionalSlides: 2,
                loopedSlides: 2,

                // Position
                slidesPerView: 'auto', //If "auto" or slidesPerView > 1, enable watchSlidesVisibility for lazy load
                spaceBetween: 20,

                // Keyboard and Mousewheel
                keyboardControl: true,
                mousewheelControl: true,
                mousewheelForceToAxis: true, // just use the horizontal axis to 

                // Lazy Loading 
                watchSlidesVisibility: true,
                preloadImages: false,
                lazyLoading: true,

            })

My question is if it’s possible to make the autoplay start just after the first image i loaded?

I realizes that if the internet is slower the slide changes with a empty div, which is not so nice…

Anyway, i am amazed with Swiper! thank you foe such a great plugin! ❤️

This is for current api

    new Swiper('.slider', {
            /** your params **/
            on: {
                lazyImageReady: function () {
                    if (!this.autoplay.running) {
                        this.params.autoplay = {
                            delay: 4000,
                            disableOnInteraction: true
                        };
                        this.autoplay.start();
                    }
                }
            }
        });

Reading docs could be really useful, look at parameters of this callback, compare loaded slide index with something. For example:

onLazyImageReady: function (s, slide) {
  if (!s.params.autoplay && $(slide.index()) === s.activeIndex) {
    s.params.autoplay = 10000;
    s.startAutoplay();
  }
}
