XnView MP stands for Multi Platform = it is available for Windows, Linux and MacOS. It is a continuation of the older XnView Classic. In my opinion it is a great alternative to Windows photos app or any Linux image viewer that comes preinstalled. I even think it is an alternative to IrfanView. It is really fast and simple to use, supports more than 500 image formats, has built in folder browser, image converter, editor... AND MORE!

I use Pix that comes stock with Linux Mint. It has a couple of different viewing modes, the one I think you want is file tree on the left and thumbnails on the main screen, you can drag and drop into folders. If you double click an image it goes to thumbnails on the left with the main part being the image. Source: about 1 year ago
