Gravatar images are commonly used for author photos and comment avatars in WordPress. By default, these images are loaded from Gravatar’s external servers, which can slow down your site and add unnecessary third-party requests.
How it works
When enabled, FlyingPress:
Scans the page for all Gravatar images (matching
gravatar.com/avatar/*)Downloads them during page caching or comment rendering
Stores them locally inside
wp-content/cache/flying-press/Serves avatars from your own domain, improving speed and reliability
Benefits
Faster page load by removing third-party avatar requests
Better privacy and reduced reliance on external services
Improved cacheability and reduced DNS lookups
Works seamlessly across posts, comments, and author boxes
Notes
Detection is automatic—no configuration needed
Cached Gravatars are updated periodically to reflect changes
Applies to all avatars using the default WordPress Gravatar system
