# Slideshow

The below commands will setup ```feh``` as a slideshow on your display. 

## Important Notes

* ```feh``` will crash if there are no photos for it to use as a slideshow
* You will likely want to tweak the ```feh``` command invocation below. These are great settings as a starting point but you'll probably want to make adjustments for your use case.
* This setup uses ```incron``` to restart ```feh``` when photos are deleted from the pictures folder. Without this piece ```feh``` will crash if a picture is removed from the pictures directory prior to ```feh``` rescaning the pictures directory.
* We default to ```DejaVuSansMono``` as the font for display of EXIF data and filename. This is an open font and looks great on most displays. Any ```fontconfig``` font can be used in its place. Adjust according to your preferences.

## Setup

``` sh

pacman -S feh imagemagick ttf-dejavu
# reload 86400 is to refresh the list of images daily -- tune for preferred number of seconds
# slideshow-delay is number of seconds (as a float) between images ; tune accordingly
