# This script assumes a dump of images from the Everyday iOS app.
# It distributes all images from images/ into N subdirectories,
# starting with 1 and proceeding to N.
# the intention is to load these images into a video editor
# to make a variant of Kalina's videos that shows multiple
# images at once.
