Images play a crucial role in web display, with several key factors affecting their appearance and performance. Here's what you need to know:

Key Display Factors:

  • File size: Maximum 20MB (recommended under 500KB for faster loading)
  • Optimal width: 2500 pixels for best quality across devices
  • Minimum width: 1500 pixels to avoid blurriness
  • Aspect ratio: Relationship between height and width
  • Container fit: Images must match their container shape to minimize cropping

Responsive Design Features:

  • Automatic creation of 7 image variations (100px to 2500px)
  • Dynamic sizing based on visitor's device
  • Responsive containers that adjust to screen size

Best Practices:

  • Upload high-quality images at or above maximum display size
  • Keep page sizes under 5MB for optimal loading
  • Use PNG format for transparent backgrounds
  • Maintain consistent aspect ratios in galleries
  • Add text as overlays rather than embedding in images
  • Include alt text for accessibility and SEO

Troubleshooting Common Issues:

  • Blurry images: Ensure width is over 1500 pixels
  • Cropping problems: Match aspect ratio to container
  • Color shifts: Check color mode and profile settings
  • Mobile display: Consider device-specific previews
  • Resolution issues: Upload at recommended dimensions

Image File Requirements:

  • Keep files under 20MB
  • Use proper file formats (JPG, PNG, GIF)
  • Maintain resolution under 120MP
  • Follow color profile specifications

For optimal performance, always save original files locally and test display across different devices before finalizing implementation.

Mobile-Specific Considerations:

  • Banner images may crop differently
  • Gallery layouts may adjust
  • Image scaling occurs automatically
  • Text overlay positioning may shift

By following these guidelines, your images will display properly across all devices while maintaining optimal site performance.
