How to Build an Image Carousel for Your Website
Want to showcase multiple images in an elegant, space-efficient way? Whether it's product photos, portfolio pieces, team members, or client testimonials, I'll show you how to create custom image carousel widgets in minutes - no coding required.
Image carousels are one of the most popular ways to display visual content. They save space, keep visitors engaged, and make your best images shine through smooth, professional transitions.
In this guide, I'll walk you through creating custom image carousel widgets using AI, focusing on building a product showcase carousel. If you're new to custom widgets, start with our complete guide on how to build custom widgets first.
Why Add Image Carousel Widgets to Your Website?
Image carousel widgets serve powerful purposes:
- Maximize Space: Display multiple images without cluttering your layout
- Showcase Products: Highlight features, angles, and details seamlessly
- Tell Visual Stories: Guide visitors through a curated visual journey
- Improve Engagement: Interactive elements keep visitors exploring
- Professional Polish: Smooth transitions create a premium feel
- Mobile-Friendly: Swipe gestures feel natural on touch devices
E-commerce sites use them for product galleries, agencies for portfolio displays, hotels for property tours. They work for any scenario where you have multiple great images competing for attention.
Building Your Custom Image Carousel with Embeddable AI
Creating image carousels with Embeddable's AI is incredibly simple. No JavaScript slider libraries, no complex configuration - just describe what you want.
Step 1: Start with Your Carousel Concept
Before you begin, think about what your carousel should display:
- Content: What images will you showcase?
- Navigation: Arrows, dots, or thumbnail previews?
- Transitions: Fade, slide, or flip effects?
- Autoplay: Should it advance automatically?
- Captions: Do images need titles or descriptions?
For our example, we're building a product showcase carousel with smooth transitions, navigation arrows, and optional captions for each image.
Step 2: Describe Your Carousel to the AI
Open Embeddable and describe your image carousel in natural language. Here's the exact prompt we'll use:
Create an image carousel for showcasing products with smooth slide transitions, navigation arrows, dot indicators, and optional captions for each image. Make it responsive and touch-friendly
The AI understands what you want and builds a complete carousel widget with:
- Smooth sliding transitions between images
- Left/right navigation arrows
- Dot indicators showing position
- Optional captions for context
- Touch/swipe support for mobile
- Responsive design that scales beautifully

Step 3: Provide Your Website URL for Design Analysis
This is where the magic happens. Give Embeddable your website URL, and the AI will:
- Match your brand colors to the carousel design
- Adapt typography for captions and labels
- Style arrows and indicators to feel native
- Ensure the carousel integrates seamlessly
The result? An image carousel that looks like it was custom-designed for your brand, not a generic slider plugin.

Step 4: Refine Your Carousel
Once the AI generates your carousel, refine it through conversation:
- "Make the navigation arrows larger and move them outside the images"
- "Change transition to fade instead of slide"
- "Add thumbnail previews below the main image"
- "Enable autoplay with 5 second intervals"
- "Add a subtle shadow around the carousel"
- "Make captions appear on hover instead of always visible"
Each change happens instantly. Watch your carousel update in real-time as you perfect every detail.
You can also use Embeddable's visual editor to adjust colors, spacing, and styling yourself.
Step 5: Test Your Carousel Interactions
Before embedding, test your carousel thoroughly:
- Test Navigation: Click arrows and dots to verify smooth transitions
- Try Touch Gestures: Swipe left/right on mobile or tablet
- Check Autoplay: Ensure timing feels right if enabled
- Verify Images: Confirm all images load correctly and look sharp
- Test Responsiveness: View on desktop, tablet, and mobile
- Caption Visibility: Make sure text is readable over images
The preview environment shows exactly how your carousel will behave on your website, so you can fine-tune before going live.

They Feel Interactive: Users engage actively by clicking, swiping, or watching autoplay - creating involvement.
They Work on Mobile: Swipe gestures feel natural and intuitive on touch devices where screen space is precious.

Best Practices for Image Carousel Design
Follow these principles for maximum impact:
Optimize Image Quality
Use high-resolution images that look sharp but compress them for fast loading
Maintain Aspect Ratios
Keep consistent dimensions across all carousel images to prevent jarring transitions
Use Clear Navigation
Make arrows and indicators obvious and easy to tap on mobile devices
Don't Over-Autoplay
If using autoplay, ensure timing is slow enough to view each image properly
Limit Slide Count
5-7 images is ideal. Too many slides means users won't see them all
Add Pause on Hover
Let users pause autoplay when they hover to examine an image
Ensure Text Contrast
If adding captions, ensure text is readable against all images in the carousel
Test Touch Gestures
Swipe should feel smooth and responsive on mobile and tablet

Show 2-3 images simultaneously for more visual information
Card-Style Carousels

Seamless continuous scrolling without hard stops
