## What it is
feh is a fast, lightweight, and highly configurable image viewer for X11, aimed at command-line users but also launchable from file managers. It supports slideshow, thumbnail, list, and multiwindow modes, filelists, custom actions, and can set X11 wallpapers.

## Use cases
- view images quickly from the terminal
- browse a directory of images as a slideshow
- generate thumbnail index sheets of image collections
- set the X11 desktop wallpaper from the command line
- list image files with dimensions like ls
- bind custom shell actions to keys while viewing images

## When to choose
- you want a minimal, fast X11 image viewer with low dependencies
- you prefer keyboard-driven image browsing from the command line
- you need a lightweight wallpaper setter or thumbnail indexer
- you run a minimal window manager setup without a full desktop environment

## When to avoid
- you need a full-featured GUI viewer with editing tools or heavy format support
- you are on Wayland without X11 compatibility
- you want a mouse-first, point-and-click photo manager
