Image resize script:
mogrify -set filename:name %t -resize 1200 -write './out/%[filename:name]_1200.jpg' *.jpg && mogrify -set filename:name %t -resize 600 -write './out/%[filename:name]_600.jpg' *.jpg
This makes a pile of duplicates and is slower but does preserve the originals
convert -set filename:name %t -resize 1200 -write './out/%[filename:name]_1200.jpg' *.jpg && convert -set filename:name %t -resize 600 -write './out/%[filename:name]_600.jpg' *.jpg
Then copy/paste all the names of the files into a txt
Add the { src: {1} },
to each line and shuffle them (todo a script)
