What happened to Photo Gallery?

When I had to have Windows 10 removed and re-installed (technical difficulties), Photo Gallery disappeared. In the apps list, it seems to have been replaced with just plain "Photos." This is not easy to use, not nearly as intuitive and in the process, I've lost pictures, downloaded duplicates and it is sorting them into folders in a different way. In short, it's really gotten my picture organization and ease of use in a mess. Does anyone know if it is possible to get Photo Gallery back?
