It has some quick controls too, along with a bunch of shortcuts such as browsing, play/pause, rotate, etc to allow for easy access. What’s good about Phiewer is that the app offers smooth transitions, and is fluid when switching between different viewports. The app is folder based, so whatever file you decide to view on it, you just need to select its parent folder, and the app will do its job, with all files available to browse in one window. In addition to allowing you to view images, the app also gives you the option to view audio and video files as well. Phiewer is a pretty standard image viewer app for Mac.
