The feh image viewer. Command line image viewer with no GUI menu interface. The qiv image also has no interface, it can be launched only from the command line. Also consider "display" which is part of both the ImageMagick and GraphicsMagick packages, so if you have them installed then you probably won't need feh or qiv.The feh image viewer. Command line image viewer with no GUI menu interface. The qiv image also has no interface, it can be launched only from the command line. Also consider "display" which is part of both the ImageMagick and GraphicsMagick packages, so if you have them installed then you probably won't need feh or qiv - although feh still has some useful functions that make it worth having. You can open a single image in feh, or you can open a folder of images which allows you to scroll through a set of images with a mouse click or by using the left and right arrow keys on your keyboard. Feh has some options that do things such as control whether Feh's window has a border, set the minimum and maximum sizes of the images you want to view, and tell Feh at which image in a folder you want to start viewing.
