Checks for lazy loading on below-fold images

| | |
|---|---|
| **Rule ID** | `images/lazy-loading` |
| **Category** | [Images](/rules/images) |
| **Scope** | Per-page |
| **Severity** | info |
| **Weight** | 3/10 |

## Solution

Use loading='lazy' on images below the fold to defer loading until needed. This improves initial page load and saves bandwidth. Native lazy loading is supported by all modern browsers. Don't lazy load above-fold images (especially LCP candidates). Consider loading='eager' for critical images.
