Universal Image Uploader

A user script that lets you paste, drag, or select images and batch-upload them to Imgur or Tikolu (selectable provider), 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.

Features (MVP)

  • 📥 Paste, drag-and-drop, or file picker to collect images
  • 📤 Batch upload to Imgur/Tikolu with progress display
  • 📋 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)

Installation

Prerequisites

Install one of the following user script managers:

Install Script

  1. Click here to install the script from GitHub
  2. Click here to install the script from Greasy Fork
  3. Click here to install the script from ScriptCat

Usage

  • 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)
  • Choose proxy via the panel’s proxy selector (default None; Imgur not supported)
  • When finished, the script auto-copies based on your selected format
  • Use history to quickly copy past uploads

Output Formats

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

Configuration

  • Per-site upload provider: remember Imgur / Tikolu
  • Per-site proxy: remember None / wsrv.nl (Imgur not supported; when wsrv.nl is selected, outputs and history copy/open use https://wsrv.nl/?url=${encodeURIComponent(url)})
  • Per-site output format: remember Markdown / HTML / BBCode / Link
  • Per-site button injection (optional): selector, position (before | inside | after), text

Site Button Settings

  • 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.

Roadmap (Planned / Not Yet Implemented)

  • 🌐 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

Changelog

v0.4.x

  • Support custom format templates.

v0.3.x

  • 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.

v0.2.x

  • 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

v0.1.0

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