What is the process to navigate through images by clicking buttons in Angular?

Looking for a solution to cycle through a series of images using previous/next buttons?

The goal is to have the image dynamically change with Angular. When one of the buttons is clicked, a different image from an array in the controller should be displayed.

This is what I attempted:

HTML -

<div>
    <md-button ng-click="switchImage(-1)"> Prev Image </md-button>
    <img ng-src="assets/img/{{image}}"/>
    <md-button ng-click="switchImage(1)"> Next Image </md-button>
</div>

Javascript/Angular -

// Array of character images
var self = this;
self.images = ['image1.gif', 'image2.gif', 'image3.gif', 'image4.gif'];
self.index = 0;
$scope.image = self.images[self.index]; // Display the first image

function switchImage(step) {
  self.index += step;
  $scope.image = self.images[self.index];
};

Seeking advice on a more effective approach to achieve this functionality?

The current setup does not update the image when the buttons are clicked. I verified that the switchImage function is not being called by placing a breakpoint and clicking the buttons.

To address the scenario where the index size reaches 0 or 4, you can adjust your code as follows:

(Additionally, ensure that you register this function in the $scope)

$scope.updateImage = function(step) {
  self.index += step;

  // If user continues to click next image and goes beyond array length
  if (self.index == self.images.length) {
     // Reset back to zero
     self.index = 0;
  } else if (self.index < 0) {
     // If user clicks previous image too many times and index becomes negative
     // Set index to the last image
     self.index = self.images.length - 1;
  }

  $scope.image = self.images[self.index];
};
