Why are images not showing in Gmail webmail but are showing in the Gmail mobile app?

Summary

Images not displaying in Gmail webmail while appearing in the mobile app can arise from numerous factors related to browser settings, network configurations, security software, and content delivery. Key areas to investigate include browser-specific issues (caching, extensions, JavaScript), VPN/proxy interference, Gmail settings, security software blocking images, CDN delivery failures, broken image links, Apple's Private Relay, and scaling/rendering problems. Additionally, recent software updates or problems with the Gmail image proxy itself could be responsible.

Key findings

  • Browser-Specific Issues: The problem is often isolated to a particular browser (e.g., Chrome), pointing to settings or extension conflicts.
  • Caching Problems: Corrupted or outdated browser cache can prevent images from loading properly.
  • Network Interference: VPNs or proxy servers can disrupt content loading within Gmail.
  • Security Software Blocking: Security software can flag and block images deemed suspicious.
  • Gmail Image Proxy Issues: Problems with the Gmail image proxy itself (HTTPS serving, blocking) can prevent images from loading.
  • Content Delivery Failures: CDN delivery failures or broken image links can cause images to fail to load.
  • Scaling or Rendering: Images are not rendering correctly at the correct size (try zooming).
  • Apple Private Relay: Apple's Private Relay (if enabled) can interfere with content delivery

Key considerations

  • Check Browser Settings: Review browser security settings, ensure JavaScript is enabled, and disable suspicious extensions.
  • Clear Browser Data: Clear browser cache and cookies to resolve caching issues.
  • Disable VPN/Proxy: Disable VPN or proxy server to see if it resolves the issue.
  • Evaluate Security Software: Check antivirus and email client settings for potential blocking of images.
  • Verify Image Sources: Ensure images are being served over HTTPS and check for CDN delivery failures; use a different CDN or host directly.
  • Verify Gmail Settings: Ensure the Gmail settings are set to 'Always show' images.
  • Recent Updates: Check for recent software updates which may have caused the issue.
  • Private Relay: Disable Private Relay, to see if that resolves the issue
  • Try Safari: Try Safari to see if that works, confirming if it is a browser specific issue.
  • Try Zooming: Try zooming in and out, to see if it's a scaling or rendering issue.
