The best way to display images on your website starts with understanding the key requirements and best practices for web-optimized images.

Image Requirements:

  • Maximum file size: 20 MB (recommended: under 500 KB for fast loading)
  • Recommended width: 2,500 pixels
  • Minimum width: 1,500 pixels to avoid blurriness
  • Supported formats: JPG, PNG, GIF
  • Color mode: RGB

Best Practices for Image Display:

  1. Size and Resolution
  • Upload high-quality images larger than your maximum display size
  • Aim for 2,500px width for optimal responsive scaling
  • Keep page size under 5MB for fast loading
  1. Image Shape and Containers
  • Match image aspect ratio to container shape
  • Use consistent aspect ratios in galleries
  • Consider how images will crop on mobile devices
  1. Format-Specific Tips
  • Use PNG for transparent backgrounds
  • Save text-heavy images as PNG to maintain sharpness
  • Use JPG for photographs and general images

Responsive Design: Images are automatically resized to seven different widths:

  • 100px
  • 300px
  • 500px
  • 750px
  • 1,000px
  • 1,500px
  • 2,500px

Accessibility and SEO:

Troubleshooting Common Issues:

  1. Blurry Images

  • Ensure proper resolution
  1. Cropping Issues
