原文外掛簡介
Images you hotlinked from third-party hosts break all the time — Imgur geo-blocked them for UK visitors and deletes them, imgbox has been throwing 503s, and Discord attachment links now expire. PixelVault Image Rescue keeps them working automatically: when a page loads it rewrites at-risk image links so they load through PixelVault’s edge instead of the failing host — and, optionally, migrates them into image hosting you own.
Instant fix, no account required. Activate the plugin and at-risk images start loading through PixelVault right away.
Reversible and non-destructive. Rewriting happens at output time only — your posts are never modified. Disable the plugin and the original markup returns untouched.
Handles src and srcset, in post content, featured images, and widgets. An optional whole-page mode also catches theme-hardcoded images.
How it works
Install and activate. Live rescue turns on by default and shows how many at-risk images it found on your site, per host.
Live rescue rewrites each at-risk image to load through PixelVault’s rescue proxy, which fetches the image once and serves it from a global edge network — so it keeps working even when the original host is blocked or down.
Migrate & Own (optional). Add a free PixelVault API key to copy every at-risk image into your own PixelVault project and rewrite your posts to permanent, owned URLs.
Which hosts
Imgur — live rescue and migrate. Geo-blocked in the UK and deletes images.
imgbox — live rescue and migrate. Intermittent 503s / possible shutdown.
Discord CDN — migrate only. Discord attachment links now expire, so live rescue can’t reliably re-fetch them; add an API key and migrate to copy them into hosting you own before they’re gone.
Two ways to rescue
Live rescue — zero setup, no account, instant. Best for keeping existing embeds visible today. It is durable-cached but re-fetches from the original host, so it can still break if that host deletes or expires the image.
Migrate & Own — a free API key copies each image into hosting you control and rewrites posts to permanent CDN URLs, independent of the original host. Fully reversible: every edited post keeps a revision, and a one-click Restore original URLs button reverts everything.
Perfect for
Blogs and forums with years of hotlinked Imgur, imgbox, or Discord images.
UK sites where Imgur images stopped loading after the geo-block.
Anyone who wants to stop depending on a third party that can block, delete, or expire their images.

External services
This plugin connects to PixelVault (https://pixelvault.dev), a third-party image-hosting service, to rehost at-risk images from Imgur, imgbox, and Discord CDN. It uses two PixelVault endpoints:
1. Rescue proxy — Live rescue (always on when enabled)
What it does: rewrites at-risk image links on your pages (Imgur and imgbox) to load through PixelVault’s rescue proxy, which fetches each image and serves it from PixelVault’s edge.
What is sent: only the URLs of the at-risk images found on the pages being rendered, sent to the rescue endpoint (default https://img.pixelvault.dev/rescue). No account or key is required.
When: each time a page containing an at-risk image is rendered.
2. Import API — Migrate & Own (optional, admin-triggered)
What it does: when you add a PixelVault API key and click Migrate all at-risk images, the plugin imports each at-risk image (Imgur, imgbox, or Discord) into your own PixelVault project and rewrites your posts to the resulting permanent URLs.
What is sent: the source image URLs to import and your PixelVault API key (sent server-side as a Bearer token), to the import endpoint (default https://api.pixelvault.dev/v1/images).
When: only while you are running a migration or restore from the plugin’s settings screen. Nothing is sent on the front end.
No visitor data and no post content beyond the at-risk image URLs themselves are ever sent. Both endpoints are configurable if you self-host PixelVault.
By using this plugin you agree to PixelVault’s Terms (https://pixelvault.dev/terms) and Privacy Policy (https://pixelvault.dev/privacy).
