✅ Best Practices

  • Use High-Quality Images – Avoid pixelation on large screens.
  • Optimize for Mobile & Desktop – Provide separate images for desktop and mobile.
  • Test Light & Dark Themes – Ensure readability of Speed Dial text in both modes.
  • Minimize File Size – Use compressed .webp files for better performance.
