Lazy load offscreen images

Lazy loading eliminates unnecessary image downloads on initial page load. A page with 20 images below the fold may transfer several megabytes of data that users who don't scroll will never see. Deferring these downloads reduces Time to Interactive, improves LCP for above-fold content, and saves bandwidth—particularly impactful for users on metered mobile connections.

Quick Reference

• Add loading="lazy" to all <img> elements below the fold
• Never lazy-load the LCP image (hero, first product image)—use fetchpriority="high" instead
• Always pair loading="lazy" with width and height attributes to prevent CLS
• Native loading="lazy" has universal support in all modern browsers—no JavaScript polyfill needed
• If fold position is unclear from the snippet, do not invent a lazy-loading defect

Check

Scan all elements in this codebase. Identify: 1) Any elements below the fold (not in the first viewport) that are missing loading="lazy". 2) Any elements marked loading="lazy" that appear to be above the fold (hero images, first product images, logos in headers). 3) Any with loading="eager" below the fold. Report the above-fold images that should NOT have lazy loading separately from below-fold images that should have it. If fold position cannot be inferred from the snippet, do not report missing lazy loading as a defect.

Fix

For images that should use lazy loading: 1) Add loading="lazy" to all elements that appear below the fold. 2) Remove loading="lazy" from any hero, logo, or first-visible image—these should load immediately. 3) Ensure all lazy-loaded images have explicit width and height attributes to prevent CLS. 4) For the LCP image specifically, add fetchpriority="high" and remove loading="lazy". Show the corrected HTML for each modified image.
