#!/bin/bash
#Author:   Malsententia <Malsententia@gmail.com>
#Purpose:  Uses a chromeless firefox window as an image viewer.
#          Inferior to most other image viewers, but good for APNGs
#          Opens kinda fast if you already have firefox running, I guess?
#Usage:    fireview image.ext
#Requires: file - gets the resolution
#          firefox - duh
#          xrandr - determines monitor resolution for max window size
#          xdotool - figures out which monitor your mouse is on, for above
#          grep,sed - also duh
#License:  WTFPL
#Notes:    I should probably break my habit of using all caps vars in my bash
