def create_square_image(filename, size=75):
    file = open(filename, 'rb')
    image = Image.open(file)
    w, h = image.size
    
    x1 = (w / 2) - (size / 2)
    x2 = x1 + size
    y1 = (h / 2) - (size / 2)
    y2 = y1 + size

    thumb = image.crop((x1,y1,x2,y2))
    thumb.save("thumb_" + filename, "JPEG")

...

of course PIL has a thumbnail method that does this type of stuff.
