The fantastic Studio Ghibli is providing stills of their famous movies for personal use.
If you wanna download them to your local machine, try using this loop:

for movie in baron chihiro ged ghiblies howl kaguyahime karigurashi kazetachinu kokurikozaka laputa marnie mimi mononoke nausicaa ponyo totoro porco; 
do 
	for number in $( seq -w 1 1 50 );
	do 
		wget https://www.ghibli.jp/gallery/${movie}0${number}.jpg; 
	done
done

Just open a shell (Bash) on your OS and paste the code above. Assuming you have “wget” installed locally, this will download those movie stills (850 pictures at the moment).
