Launch the Image-Infused Modal

Question

Launch the Image-Infused Modal

I am completely new to the world of Ionic development.

Currently, I am working on a simple Ionic application that comprises a list of users with their respective usernames and images stored in an array.

Typescript:

  users = [
    {
      "name": "First User",
      "image": [
        "https://ionicframework.com/img/ionic-logo-blog.png", "https://ionicframework.com/img/ionic_logo.svg", "https://ionicframework.com/img/ionic-logo-blog.png"
      ]
    },
    {
      "name": "Second User",
      "image": [
        "https://ionicframework.com/img/ionic-logo-blog.png", "https://ionicframework.com/img/ionic_logo.svg", "https://ionicframework.com/img/ionic-logo-blog.png"
      ]
    },
    {
      "name": "Third User",
      "image": [
        "https://ionicframework.com/img/ionic-logo-blog.png", "https://ionicframework.com/img/ionic_logo.svg", "https://ionicframework.com/img/ionic-logo-blog.png"
      ]
    },
  ]

HTML:

<div *ngFor="let user of users">
    <span> {{ user.name }} </span> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
<button ion-button type="button" (click)="openDocument(user.image)"> View Image </button>
    <br>
</div>

Live Example: https://stackblitz.com/edit/ionic-1tzycv

In the example above, there is a button labeled View Image. When clicked, I aim to display each image in a modal window sequentially with next and previous buttons to navigate through them.

I have scoured various resources but have not found a solution for displaying multiple images from an array within a modal as demonstrated in this code snippet:

this.modalCtrl.create(SomePage, {}, { enableBackdropDismiss: false }).present();

How can I achieve this functionality where upon clicking the View Image button, a modal opens showing all the images one by one with options to navigate via next and previous buttons?

I am looking for something similar to this reference implementation: https://codepen.io/anon/pen/NoGVGb, however, I need it specifically tailored for Angular 6 with Ionic 3.
