  <ion-slides class="index-adv idslides" pager="true" [options]="slideOpts">
    <ion-slide>
      <div text-center routerLink="/original">
        <img src="assets/images/author_pic.jpg">

    </ion-slide>
  </ion-slides>

  slideOpts2 = {
    centeredSlides: true,
    loop: true,
    preloadImages: false, // Disable preloading of all images
    lazy: true, // Enable lazy loading
    slidesPerView: 1.14,
    spaceBetween: 5
  };

You can’t jump to the page when you get to the last one. I know that this { loop: true,}is affected, but I don’t know how to change it.
