For the WordPress.org plugin repository, you need to create:

1. banner-772x250.jpg - Used on plugin page header
2. banner-1544x500.jpg - High-resolution version for retina displays

These should be placed in this assets directory.

Design tips:
- Keep text minimal
- Use clear, high-quality images
- Ensure the banner communicates what the plugin does
- Use consistent branding with your icon
