a simple script to get an arbitrary number of sample images from unsplash, organized by aspect ratio

get_images.sh

#!/bin/sh

mkdir -p example_images/landscape
mkdir -p example_images/portrait

loop=0
iterations=50

while [ $loop -lt $iterations ]; do
  x=$(( $RANDOM % 950 + 50 ))
  y=$(( $RANDOM % 950 + 50 ))
  name="$( echo "scale=2; ${x} / ${y}" | bc )-to-1"
  
  if [[ x -gt y ]]; then
    dir="landscape"
  else
    dir="portrait"
  fi
  
  wget http://unsplash.it/${x}/${y} -O ./example_images/${dir}/\(${name}\)_${x}x${y}.jpg

  loop=$((loop+1))
done
