A slideshow of images can add visual appeal and interactivity to web pages. Using JavaScript, it’s possible to create a dynamic slideshow that cycles through a collection of images. Let’s explore how to create a simple yet effective image slideshow using JavaScript.

HTML Structure

Start with a basic HTML structure containing an element to display the images:

<div class="slideshow-container">
  <div class="slides">
    <img src="image1.jpg" class="slide-image" />
    <img src="image2.jpg" class="slide-image" />
    <img src="image3.jpg" class="slide-image" />
    <!-- Add more image elements as needed -->
  </div>
</div>

JavaScript Logic

1. Implement Slideshow Functionality

let slideIndex = 0;
const slides = document.getElementsByClassName('slide-image');

function showSlides() {
  for (let i = 0; i < slides.length; i++) {
    slides[i].style.display = 'none';
  }
  slideIndex++;
  if (slideIndex > slides.length) {
    slideIndex = 1;
  }
  slides[slideIndex - 1].style.display = 'block';
  setTimeout(showSlides, 2000); // Change image every 2 seconds (adjust as needed)
}

showSlides();

• slideIndex keeps track of the current slide.
• slides collects all image elements with the slide-image class.
• showSlides() hides all images and displays one image at a time by changing its display style property.
• setTimeout() is used to call the showSlides() function at regular intervals, creating a continuous slideshow effect.

CSS Styling (Optional)

Style the slideshow container and images for better presentation:

.slideshow-container {
  position: relative;
  max-width: 100%;
}

.slides {
  display: none;
}

.slide-image {
  width: 100%;
  height: auto;
}

Conclusion

Creating a simple image slideshow using JavaScript enhances the visual experience of web pages, providing an engaging way to present images. The provided JavaScript logic cycles through a collection of images, creating a continuous slideshow effect.
