The Double-Click Image Opener plugin adds a simple desktop-style action for images inside your vault by opening them in the system's default image viewer when you double-click them. It is built for quick access rather than in-app editing, which makes image-heavy notes easier to inspect without extra menu steps or manual file navigation. The behaviour works across reading, live preview, and source mode, so the interaction stays consistent wherever you view a note. The plugin also supports common image formats such as PNG, JPG, GIF, WebP, and SVG, and it is designed to run across Windows, macOS, and Linux. There is also an optional setting to show a success notification after an image is opened.
