## Description

Process selected images, MP4/MOV videos and platform share links from Tools > 550W.
Choose a local upload or Media Library attachment. Video erasing is full-frame unless
you use the advanced rectangle option. Manually check task receipts and open resolved
video links in the browser to download. Original attachments are never overwritten.

This plugin uses the external 550W service at https://www.550wai.cn/. Explicit OAuth
connection uses /oauth2/ and the resource /media-api/global; processing uses /media-
api/global/v1/ or /open/ for API Key access. Selected media, links, task IDs and
necessary credentials are transmitted only for your chosen operation. API keys are
never saved. OAuth tokens are encrypted in user metadata, bound to the current administrator,
site auth salts and region. Up to 20 task receipts are kept per user/region; the
last 7 days are shown and receipts can be cleared. No original media paths or source
links are stored in receipts. No unrelated telemetry, remote scripts, automatic 
polling or paid retries. Each charged operation requires explicit confirmation. 
Use only media you have rights to process.

Global service/account: https://eraser.550wai.com/
 Privacy policy: https://eraser.
550wai.com/privacy/ Terms of service: https://eraser.550wai.com/terms/ Review the
applicable service terms/privacy notices before transmitting media. Do not use images
or videos without the necessary rights.

## Installation

 1. Install the ZIP using Plugins > Add New > Upload Plugin.
 2. Confirm outbound HTTPS and PHP/WordPress upload limits allow the selected file.
    Native HTTP multipart transfers are capped at 64 MiB and may be lower according
    to available PHP memory. Use the web processing tool for larger files.
 3. Open Tools > 550W and connect using OAuth, or enter API credentials for each request.
    OAuth requires HTTPS (or 127.0.0.1 during local acceptance) and PHP sodium.
 4. Select your media, confirm credit usage, and process. Query existing tasks before
    repeating a request with an unknown outcome. This release requires administrator
    permission (manage_options); connections are not shared site-wide.
