A user script that lets you paste, drag, or select images and batch-upload them to Imgur or Tikolu or MJJ.Today or Appinn (selectable provider), optionally converting to WebP, then auto-copy the result in Markdown/HTML/BBCode/plain link. It also integrates configurable site buttons (works with SPA pages) and keeps a local upload history for quick reuse.

中文版

• 📥 Paste, drag-and-drop, or file picker to collect images
• 📤 Batch upload to Imgur/Tikolu/MJJ.Today/ImgBB/Appinn/Photo.Lily/111666.best/Skyimg/StarDots with progress display
• 🔄 Support concurrent upload to a secondary backup host (Dual-upload)
• 🖼️ Optional WebP conversion via proxy or supported hosts
• 📋 Auto-copy output in Markdown / HTML / BBCode / Link
• 🕘 Local history to quickly re-copy and reuse uploads
• 🔘 Optional site button injection with SPA observer (per-site settings)

• Requires a user script manager:
  • Tampermonkey
  • Violentmonkey
  • ScriptCat
• Install from: Greasy Fork · ScriptCat · GitHub

• Open any site, paste or drop images onto the page, or use the panel’s file picker
• Watch the upload queue and progress
• Choose upload provider via the panel’s host selector (Imgur/Tikolu/MJJ.Today/ImgBB/Appinn/Photo.Lily/111666.best/Skyimg/StarDots)
• (Optional) Choose a secondary host for dual-upload and automatic fallback
• Choose proxy via the panel’s proxy selector (default None)
• Toggle WebP option to convert images via proxy
• When finished, the script auto-copies based on your selected format
• Use history to quickly copy past uploads

• Markdown: ![alt](url)
• HTML: <img src="url" alt="alt" />
• BBCode: [img]url[/img]
• Link: url

• Open the panel and switch to "Settings".
• Enter a CSS selector for the target element (e.g., .comment-screenshot-control).
• Choose position: Before inserts before, After inserts after, Inside appends as the last child.
• Set button content: plain text or a single-root HTML snippet. Leaving it empty uses the localized default.
• Click Save & Insert to persist the rule locally and inject immediately. A DOM observer keeps it inserted on SPA pages.
• Use Remove button (temporary) to clear injected buttons without deleting rules.
• Use Clear settings to remove all saved rules.
• Each rule in the list supports Edit and Delete.
• Tips: prefer stable, unique selectors to avoid multiple insertions.

• 🌐 Multi-provider uploads: SM.MS, Cloudflare Images, self-hosted S3/MinIO
• 🛠 Image processing options: quality, resize, compression, format (JPEG/PNG/WebP), EXIF removal
• 📦 Queue controls: concurrency slider, retry/backoff, cancel/pause
• 🧩 Template system: fully customizable output formats and HTML snippets
• 🗂 History enhancements: filters by time/provider/tags, batch copy, faster reuse

• New provider: Added StarDots image hosting support. Requires configuration of API Key, Secret, and Bucket name in the settings panel.
• Fix: Refactored StarDots settings UI to use c function instead of innerHTML for better compatibility with CSP-restricted sites.

• Fix: Optimized site button detection logic to prevent duplicate insertions when the page DOM changes (e.g., dynamic toolbar updates).
• Multi-host support:
  • Added ability to upload to a secondary host concurrently.
  • Implemented proxy chain fallback: uses primary host by default, falls back to secondary host if primary fails or via proxy chain.
  • Updated proxy chain strategy: Primary(Proxy) -> Secondary(Proxy) -> Primary(Direct).
  • UI Improvements: Distinct color themes for primary (blue) and secondary (purple) host controls and tags.

• Enhanced wsrv.nl proxy: appends &output=webp when WebP option is enabled.

• Added new upload providers: ImgBB, Photo.Lily, 111666.best, and Skyimg.
• Updated documentation and host selector to include the new providers.
• Aligned 111666.best proxy behavior with Imgur (supports wsrv.nl -> DuckDuckGo).
• Improved history panel: larger thumbnails, lazy-loaded previews, and a floating enlarged preview when hovering thumbnails.
• Optimized log list style: improved spacing, added background/border for better visibility, and hover highlight effects.
• Added Skyimg (WebP) variant that uploads with ?webp=true.
• Enhanced wsrv.nl proxy: for GIF files (based on original filename) append &n=-1.

• Feature: Comprehensive iframe support.
  • The upload panel is displayed only in the top frame.
  • Site buttons are injected into all frames (including iframes).
  • DOM changes in iframes are monitored for button injection.
• Fix: Cross-frame focus tracking.
  • Correctly handles file picker requests and image pasting from iframes.
  • "Copy" button correctly targets the last focused element, even inside iframes.
• Optimization: Refactored drag-and-drop logic.
  • Unified drag-and-drop initialization for both main frame and iframes, reducing code duplication.
  • Drag-and-drop settings changes now sync instantly across frames via addValueChangeListener.
• Optimization: Unified paste upload behavior across frames.
  • Paste events in both the main frame and iframes now use the same iu:uploadFiles pipeline as drag-and-drop, so behavior is consistent regardless of where you paste.
• Feature: Mock upload host for testing.
  • Optional test host that simulates a 1-second delay and returns a random demo image URL.
  • Controlled via an internal flag and disabled by default for normal users.
• Fix: Drag overlay flicker over inputs.
  • The drop overlay is now pointer-events: none and only toggles visibility on valid drag targets, avoiding oscillation when dragging across input fields.

• Added new proxy options: DuckDuckGo and wsrv.nl -> DuckDuckGo.
• Enabled proxy selection for Imgur (supports DuckDuckGo and wsrv.nl -> DuckDuckGo; wsrv.nl automatically switches to wsrv.nl -> DuckDuckGo).
• Refactored proxy configuration logic for better extensibility.

• Add simulated addValueChangeListener support for script managers that do not implement it natively, enabling cross-tab data synchronization.
• Optimization: Add polling mechanism as a fallback for data synchronization when native listeners are unavailable.
• Refactoring: Migrate all synchronous GM_ storage calls to asynchronous APIs to improve script performance and compatibility with modern environments.

• Fix compatibility issues with utags-shortcuts
• Refactoring: use esbuild to bundle the script

• Per-site enable toggle via command menu; refresh page to apply.
• Per-site paste and drag-and-drop toggles in Settings; preset sites default to enabled.
• Support pasting multiple images at once.
• Paste/drag toggles take effect immediately without page reload.
• Insert upload-status placeholders into the target input and replace on success/failure.

• Add MJJ.Today upload provider.
• Add Appinn upload provider.

• Support custom format templates.
• Switch Imgur upload from fetch to GM_xmlhttpRequest to avoid CORS.
• Extract shared gmRequest helper to unify upload provider requests.

• Settings storage migrated to a unified per-site map, consolidating previously separate keys into a single structure. Example shape: { format?, host?, proxy?, btns?: [...] }.
• Panel UI is now rendered inside a Shadow DOM for style isolation from host sites. Internal styles use :host; the drop overlay (#uiu-drop) and site-injected buttons (.uiu-insert-btn) remain in the page DOM.
• Added clear “open” visuals and accessibility states (aria-pressed) for History and Settings toggles.
• Shadow-DOM-aware focus tracking: resolves editable targets inside nested open shadow roots and same-origin iframes; excludes the script’s panel from being tracked as a target.
• Trusted Types compliance: avoid innerHTML clears (use textContent = ''), and parse custom button HTML via Range.createContextualFragment to prevent TT violations on strict sites.
• Backward compatibility: existing settings are migrated automatically; no manual action required.

• Added proxy option: None / wsrv.nl; Imgur not supported; when wsrv.nl is selected, outputs and history copy/open use https://wsrv.nl/?url=${encodeURIComponent(url)}
• Added Tikolu upload provider; choose Imgur/Tikolu via panel host selector
• Added last-focused input tracking: when clicks cause focus loss (e.g., upload), insert into the last visited input and restore focus; improved caret fallback for contentEditable elements

• Initial MVP: Imgur upload, batch & progress, auto-copy (Markdown/HTML/BBCode/Link), local history, SPA-aware button injection
