Index your media folders once — then browse the full thumbnail gallery at any time, even with the source drives offline.
PSI — Pict Snap Index is a lightweight media gallery tool. It scans your folders, generates thumbnails, and stores them locally — so you can browse thousands of images and videos anytime, even when the source drives are disconnected.
Perfect for archiving external drives, reference libraries, or any media collection you want to keep accessible without mounting the original storage.
Cross-platform: works on Windows and macOS.
