Img Cleanup — Selective attachment cleanup

Obsidian plugin that detects images and attachments that became unlinked from a note while you edit it, and offers to send them to the trash — respecting Obsidian's trash settings and keeping a trace log of every action.

Features

• Live detection: listens for changes in the vault's .md files (with a 1.5 s debounce so it doesn't interrupt while you type) and compares attachments referenced before/after.
• Supported formats: ![](path), ![[file]], [[file]] and Markdown links. External URLs are ignored.
• Watched folders only: defaults to .img/ (configurable in Settings); any attachment outside those folders is ignored.
• Backlinks: if another note still references the file, it is not offered for deletion.
• Batch modal: a single window lists the unlinked files with a checkbox per file and Delete / Keep buttons.
• "Don't ask again": persists the last action as a permanent policy (always delete / always keep). Resettable from Settings.
• Obsidian's trash: uses fileManager.trashFile() — never permanently deletes against the user's trash configuration.
• Trace log: JSONL with date, file, source note, destination and action. Rotated with a 1000-entry cap. History viewable from a modal (open file / clear).

Installation

1. Create the folder .obsidian/plugins/img-cleanup/ inside your vault.
2. Copy manifest.json and main.js into it (already compiled in this repo).
3. Restart Obsidian → Settings → Community plugins → enable Img Cleanup.

Configuration (Settings → Img Cleanup)

Watched folders	Comma-separated paths (default .img/). A bare name matches at any depth

The log lives in .obsidian/plugins/img-cleanup/data/appendix-log.jsonl.
