原文外掛簡介
Sidcraft Cloud Media Offload frees up your hosting space by moving every file you upload to the Media Library into your own cloud storage. It works in the background and is transparent: you upload media exactly as before, WordPress creates its image sizes, and the plugin moves the original and every generated size to the cloud, then serves them from there.
Offloading
Cloud drives: Dropbox, OneDrive, OneDrive for Business / SharePoint document libraries, Google Drive, Box and iCloud (Apple CloudKit).
Object storage & CDN: Amazon S3 (and S3-compatible services), DigitalOcean Spaces (optional Spaces CDN), Bunny.net Storage + CDN (with token authentication) and Cloudinary.
Video platforms: send video uploads to Cloudflare Stream, Mux, Vimeo or YouTube while all other files go to your main storage. Videos are shown with the platform’s player in the video block and the shortcode.
Automatic: new uploads (originals, scaled images and every thumbnail size) move to the cloud right after upload.
Large files are moved in the background with WP-Cron, using each provider’s chunked/resumable upload API.
Optional: keep a local backup copy, or delete files from wp-content/uploads to save space.
Choose which file types to offload (all, images, media, or a custom extension list) and which to always keep local.
Image editor and thumbnail regeneration keep working: edited files are pushed to the cloud automatically.
Deleting a file from the Media Library also deletes (trashes) the cloud copy – optional.
Media Library “Storage” column, row actions and bulk actions: move to cloud, move back, download local copy, remove local copy.
Existing uploads: offload your whole existing library (originals plus every thumbnail size) with one click and a progress bar – from the Cloud Media dashboard, the Offloading settings or the Tools screen – or let it run in the background with WP-Cron.
Tools screen to create public links, download local copies or move everything back to the server.
WP-CLI: wp sidcm offload --all, wp sidcm restore --all, wp sidcm status.
Delivery & security
Offloaded files get stable URLs on your own domain (for example https://example.com/cloud-media/2026/10/photo.jpg) that mirror the uploads structure, so responsive images (srcset), the block editor and other plugins keep working.
Secure mode (default): every request is redirected to a short-lived, signed link created by the provider. Cloud files stay private.
Public mode: permanent “anyone with the link” shares for the fastest delivery (Dropbox, Google Drive, Box).
Per-file access: restrict any attachment to logged-in users.
Existing post content that still points to wp-content/uploads is rewritten to the cloud URLs.
OAuth tokens and client secrets are encrypted at rest. Each site uses its own cloud apps – files never pass through a third-party relay.
Cloud modules (shortcode & block)
Show any folder of your cloud storage on a page with the Cloud Module block or the [sidcm_cloud] shortcode:
File browser with breadcrumbs, search and sub-folder navigation (scope-locked to the configured folder)
Image gallery with lightbox, and image carousel
Download list and single download button
Audio and video players with playlists, streamed from the cloud
Document embed (Office and PDF previews where the provider supports it)
Upload box with drag & drop; files go directly from the visitor’s browser to the cloud where the provider allows it (Dropbox up to 150 MB, OneDrive and Google Drive any size, Box up to 50 MB), otherwise in chunks through your server
Personal folders: folder="Clients/%user_login%" shows every logged-in user only their own folder – ideal for client portals
Role-based access, password protection, e-mail notifications on uploads and downloads
Integrations
WooCommerce downloadable products and Easy Digital Downloads files are delivered from the cloud: after the store verifies the purchase, the customer is redirected to a short-lived cloud link. Store files are never public. A cloud file picker creates “store links” for any file in your cloud storage.
Sidcraft Commerce: sell digital downloads from the cloud. Attach cloud files to products; when an order is paid, customers get secure links (with download limits and expiry) in their order e-mail and on a [sidcm_my_downloads] page. Links are revoked if the order is cancelled or refunded.
Sidcraft Page Builder: a native “Cloud Module” unit with every module type.
Contact Form 7, WPForms, Gravity Forms and Fluent Forms: files uploaded through forms are copied to the cloud automatically (with an optional e-mail containing the links).
Cloud Media dashboard
The plugin has its own dashboard (Cloud Media → Dashboard) with storage figures, one-click offloading of existing uploads, connected accounts, integrations, recent activity and quick links.
Activity log & statistics
Track offloads, uploads, downloads and errors; see the most downloaded files over the last 30 days. Logged data is included in WordPress’ personal data export and erase tools.
External services
This plugin connects to the cloud storage services that an administrator chooses to connect. Nothing is sent to any service until an administrator enters their own app credentials and clicks “Connect”. No data is sent to the plugin author.
What is sent and when:
When connecting an account (OAuth): the administrator’s browser is sent to the provider’s sign-in page; the site then exchanges the returned authorization code for access tokens.
When a file is uploaded to the Media Library (or moved with the Tools page / WP-CLI): the file and its generated image sizes, with their file names, are uploaded to the connected account.
When an offloaded file is viewed or downloaded: the site requests a temporary download link from the provider, and the visitor’s browser downloads the file directly from the provider (which receives the visitor’s IP address and browser information). In Google Drive private mode the file is downloaded by the site and streamed to the visitor.
When a Cloud Module is displayed or used: the site lists the configured folder; files are delivered as above; files uploaded by visitors through an upload box are sent to the configured folder.
When a Media Library file is deleted (if enabled): a delete/trash request is sent for the cloud copy.
