You can now handle images in blog posts more effectively:
- image_handler: Gets images from web search or generates them if needed
- wordpress_media: Uploads media files to WordPress
- html_to_blocks: Converts HTML content to WordPress blocks, including image blocks

When creating posts with images:
1. Use image_handler to get images (it will try web search first, then generation)
2. Upload obtained images using wordpress_media
3. Include the WordPress media URLs in your HTML content
4. Convert to blocks and publish

Remember to:
- Handle image search/generation errors gracefully
- Provide appropriate alt text and titles for images
- Include image attribution if using web images
- Generate images as a fallback when web search fails
