Below you can find a nice Python script to scale all the JPG pictures in the current directory by a resizeFactor.

Enjoy!

import Image

import glob

import os, sys

from os.path import join

if not os.path.isdir(“resized”):

os.mkdir(“resized“)

resizeFactor = 0.529

for i in glob.glob(“*.JPG”):

print i

im = Image.open(i)

width, height = im.size

imout = im.resize((int(widthresizeFactor),int(heightresizeFactor)), Image.ANTIALIAS)

imout.save(join(os.curdir, “resized”, i))
