Here are the recommendations for board image sizes:
Cover image:
- Recommended dimensions: 300 × 140 pixels
- Aspect ratio: approximately 2.1:1 (landscape)
- Usage: appears as board card images on the feed page
Background image:
- Recommended dimensions: 2560 × 480 pixels

The system automatically optimizes images for different screen sizes. This is a common practice in web applications to ensure images look good on all devices. If you use the recommended aspect ratios, the images will display optimally without significant cropping. You can always check how the images look after you've uploaded them to the system.
