1、Image Previews
Since 1.6.0, ranger can preview images in full color. This works by calling a program named w3mimgdisplay that's included in the w3m web browser, which draws images directly into the terminal.
archlinux install w3m
pacman -S w3m
NEW
~/.config/ranger/rc.conf
Add the line
set preview_images true
2、colorscheme
Add the line to /rc.conf
set colorscheme default
colors :default jungle snow solarized
