A fast, private photo gallery and image viewer for Windows 10 and 11 with a random slideshow that never repeats an image until it has shown them all, even after you close and reopen it. It's like a true shuffle for your photo folders, wallpapers and digital photo frame setups.
Get Unique Gallery from the Microsoft Store (available from 19 November 2026). You can also get it as a portable download with no install needed.
- Unique slideshow: random order (or your sort order), and no image repeats until every image in the folder has been shown. It remembers where it left off between sessions, and new photos join the rotation automatically.
- Handles big folders: smooth with tens of thousands of images, including subfolders.
- HDR support: real HDR on HDR displays, and tone-mapped HDR (JPEG XR / JXR) on standard screens.
- Viewer: fullscreen, keyboard, mouse-wheel and back/forward-button navigation, with an adjustable slideshow interval.
- Formats: JPEG, PNG, GIF, BMP, TIFF, JPEG XR, plus WebP, HEIC and AVIF with the free Windows codec extensions.
- Private by design: no accounts, no internet, no telemetry. Slideshow history and the optional thumbnail cache stay in a hidden folder next to your photos.
