Before uploading images to your website, consider these essential formatting guidelines:

Image Requirements:

  • Maximum file size: 20 MB (recommended: under 500 KB for faster loading)
  • Minimum width: 1500 pixels (recommended: 2500 pixels)
  • Supported formats: JPG, PNG, GIF
  • Color mode: RGB
  • File size limit for optimal page load: Keep total page size under 5 MB

Best Practices for Image Display:

  1. Image Width
  • Desktop: Minimum 1500 pixels wide to prevent blurry display
  • Upload high-quality images larger than intended display size
  • Optimal width: 2500 pixels for maximum quality across devices
  1. Aspect Ratio
  • Maintain consistent ratios within galleries
  • Match image shape to container requirements
  • Common ratios: 16:9, 4:3, 1:1 (square)
  1. Transparent Backgrounds
  • Use PNG format for transparency
  • Edit transparency before uploading
  • Avoid in-platform editing for transparent images
  1. Text on Images
  • Add text as overlay instead of embedding
  • Use PNG format for images containing text
  • Ensure text remains readable across devices
  1. Mobile Optimization
  • Images automatically scale for different devices
  • Seven responsive variants created (100px to 2500px)
  • Preview using device view before publishing

Troubleshooting Common Issues:

  1. Blurry Images:
  • Check image width (minimum 1500px)
  • Verify file format and compression
  • Review original image quality
  1. Color Distortion:
  • Ensure RGB color mode
  • Check color profile settings
  • Verify file format compatibility
  1. Cropping Issues:
