原文外掛簡介
OffloadForge copies your WordPress media library, including images, videos, and documents, to a cloud storage provider of your choice and rewrites the URLs so files are served from the cloud or your CDN. This can reduce load on your web server and take advantage of the provider’s global delivery network.
It works with three providers: Amazon S3, DigitalOcean Spaces, and Google Cloud Storage (via HMAC keys). There is no SDK or Composer step to install; the plugin talks to each provider’s REST API using WordPress’s built-in HTTP functions with AWS Signature V4 request signing.
This plugin is a third-party integration and is not affiliated with, endorsed by, or sponsored by Amazon, DigitalOcean, or Google. “Amazon S3”, “DigitalOcean Spaces”, and “Google Cloud Storage” are trademarks of their respective owners.

CDN & Performance Optimization
Seamless CloudFront and custom CDN integration
Full URL rewriting — post content, srcset, thumbnails, theme templates, headers, footers
Output buffer rewrites all frontend HTML — catches even hardcoded theme URLs
Smart re-link — detects files already in cloud, skips re-upload
Global content delivery for faster load times
Reduced server bandwidth and hosting costs
Built-in Repair & Diagnostic Tools
Fix Permissions — Scans all offloaded files and detects 403 AccessDenied errors. One-click fix sets public-read ACL or re-uploads with correct permissions. Essential after bulk operations or bucket policy changes.
Fix Thumbnails — Finds offloaded images where thumbnail sizes are missing from the cloud. Common after bulk offload interruptions or when WordPress generates new image sizes. Uploads missing thumbnails and stores their cloud URLs so all image sizes load correctly.
Fix URLs — Detects when your CDN URL, bucket, or region settings changed but stored media URLs still point to the old location. Bulk-updates all stored URLs to match current settings without re-uploading. Essential after migrating between providers or changing CDN configuration.
Each repair tool follows a Scan > Review > Fix workflow with real-time progress tracking.

Performance Notes
Serving media from a cloud provider or CDN moves that traffic off your web server and can deliver files from a location closer to the visitor. Actual results depend on your host, your provider, your CDN configuration, and your theme, so this plugin does not promise any specific speed, SEO, or ranking outcome.
External services
This plugin is a cloud-storage offloading service: it connects to the cloud provider you choose, using your own account credentials, and uploads your media there so the files can be served from that provider or your CDN. It connects only to the bucket and region you configure on the settings screen. No media or credentials are ever sent to the plugin author or any other party. Depending on your configuration, it relies on one of the following third-party services:
Amazon S3

– Data sent: Your media files (images, videos, documents), filenames, and MIME types are sent securely to Amazon S3 whenever you upload a new file or use the bulk offload tool.
– Terms of Use: AWS Service Terms
– Privacy Policy: AWS Privacy Notice
DigitalOcean Spaces
Used to store and serve your media files globally.
– Data sent: Your media files (images, videos, documents), filenames, and MIME types are sent securely to DigitalOcean whenever you upload a new file or use the bulk offload tool.
– Terms of Use: DigitalOcean Terms of Service
– Privacy Policy: DigitalOcean Privacy Policy
Google Cloud Storage
Used to store and serve your media files globally.
– Data sent: Your media files (images, videos, documents), filenames, and MIME types are sent securely to Google Cloud Storage whenever you upload a new file or use the bulk offload tool.

Privacy Policy
This plugin does not collect or store any personal data. All cloud storage credentials are stored in your WordPress database and are only used to communicate with your chosen cloud storage provider. No data is sent to third parties except your selected cloud provider.
