How to bulk resize JPEG pictures via Imagemagick

Sometimes you need to reduce the size of many pictures, for example to share them on the internet.

A nice way of doing this is via Shell:

convert FILE.JPG -resize 2448x1836 ./smaller_pictures/FILE.JPG

do

convert $F -resize 2448x1836 ./smaller_pictures/$F
done
