Every folder contains either images or a shell script to generate
images. In some of the folders there is a script called crop.sh to
generate cropped versions of the images in the same folder. Once all
images and crops have been generated, the script in the folder
montage can be used to generate a large montage of all crops. You
will need ImageMagick ("apt-get install imagemagick" on Debian and
Ubuntu). And for the generation of the montage, you will have to
relax ImageMagick's security policy (/etc/ImageMagick-6/policy.xml),
because the montage is so large.
