Image optimization analysis for SEO and performance. Checks alt text, file sizes, formats, responsive images, lazy loading, and CLS prevention. Use when user says "image optimization", "alt text", "image SEO", "image size", or "image audit".

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Image Optimization Analysis

## Checks

### Alt Text
- Present on all `<img>` elements (except decorative: `role="presentation"`)
- Descriptive: describes the image content, not "image.jpg" or "photo"
- Includes relevant keywords where natural, not keyword-stuffed
- Length: 10-125 characters

**Good examples:**
- "Professional plumber repairing kitchen sink faucet"
- "Red 2024 Toyota Camry sedan front view"
- "Team meeting in modern office conference room"

**Bad examples:**
- "image.jpg" (filename, not description)
- "plumber plumbing plumber services" (keyword stuffing)
- "Click here" (not descriptive)

### File Size

**Tiered thresholds by image category:**

| Image Category | Target | Warning | Critical |
|----------------|--------|---------|----------|
| Thumbnails | < 50KB | > 100KB | > 200KB |
| Content images | < 100KB | > 200KB | > 500KB |
| Hero/banner images | < 200KB | > 300KB | > 700KB |

Recommend compression to target thresholds where possible without quality loss.

### Format
| Format | Browser Support | Use Case |
|--------|-----------------|----------|
| WebP | 97%+ | Default recommendation |
| AVIF | 92%+ | Best compression, newer |

How to install

The exact contents, by fingerprint

mdr add hashgraph-online/awesome-codex-plugins/seo-images@sha256:36bd4697abf90bc3

The line at the top of this page pins the label v1.7.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
