Implementation

Core Script (scripts/generate-images-with-ideogram.js)

• Reads existing image-prompts.json and generates images via Ideogram.ai API v3
• Native Node.js implementation (no additional dependencies)
• Command-line options: --limit, --year, --skip-existing
• Built-in rate limiting and error handling

GitHub Secret Setup Documentation

• Explicit permissions (contents: write)
• Auto-commit generated images

Integration

• Added generate-blog-images npm script to package.json
• Updated README.md with usage examples
• Updated scripts/IMAGE-GENERATION-README.md with new automation option
