This tool performs a comprehensive audit of website images to ensure optimal SEO and web performance. It checks for proper alt text descriptions, recommends modern formats (WebP, AVIF), validates file sizes, and verifies responsive image implementation using `srcset` and `sizes`. Furthermore, it guides best practices for lazy loading, prioritizing LCP images, and preventing Cumulative Layout Shift (CLS) by checking for dimensions.

This skill guides developers through advanced techniques to optimize Shopify store performance and improve Core Web Vitals (LCP, CLS, INP). It covers fixing lazy-loaded hero images, migrating to the modern `image_url` filter for responsive images, profiling slow Liquid renders, and optimizing font delivery, ensuring a fast and professional e-commerce experience.
