Validates `<picture>` elements have required `<img>` fallback

| | |
|---|---|
| **Rule ID** | `images/picture-element` |
| **Category** | [Images](/rules/images) |
| **Scope** | Per-page |
| **Severity** | error |
| **Weight** | 6/10 |

## Solution

Every `<picture>` element MUST contain an `<img>` child element as fallback.

Correct structure:
`<picture>`
  `<source srcset="image.webp" type="image/webp">`
  `<source srcset="image.jpg" type="image/jpeg">`
  `<img src="image.jpg" alt="Description">`
`</picture>`

The `<img>` provides fallback for:
- Browsers without `<picture>` support
- Screen readers
- Search engine crawlers
- Failed srcset loading
