How do I optimize images for Cyber Monday?

As an e-commerce professional preparing for Cyber Monday, I'm struggling to understand how to optimize my product images to maximize conversions and sales. I know visual presentation is critical during high-traffic shopping events, but I'm unsure about the technical specifications, design strategies, and performance optimization techniques that will make my product images stand out and drive more purchases. I need a comprehensive strategy that covers image quality, loading speed, mobile responsiveness, and psychological triggers that encourage buying behavior.

TL;DR - Quick Answer

Optimize Cyber Monday images by compressing all product photos to under 150KB (use WebP format), use responsive image srcsets so mobile devices load smaller files, and enable lazy loading for below-the-fold images. These changes alone can cut page load time by 40-60% under high traffic.

Optimizing Images for Cyber Monday

Images are typically the largest contributor to slow page load times. On Cyber Monday, when traffic spikes and every second of load time costs conversions, image optimization is one of the highest-impact technical changes you can make.

Image Optimization Checklist

-Convert all product images to WebP format (30-50% smaller than JPEG at same quality)
-Compress all images to under 150KB before upload; hero banners under 300KB
-Use responsive srcset attributes so mobile gets 400px images, not 1200px
-Enable lazy loading for all images below the fold (loading="lazy" attribute)
-Set explicit width and height attributes on images to prevent layout shifts
-Preload hero banner and first-visible product images with <link rel="preload">
