path = raw_input("path:")
width =int(raw_input("the width U want:"))
imgslist = glob.glob(path+'/*.*')
format = raw_input("format:")
def small_img():
	for imgs in imgslist:
		imgspath, ext = os.path.splitext(imgs)
		print imgs
		img = Image.open(imgs)
		(x,y) = img.size
		print x,y
		height =int( y * width /x)
		print height
		small_img =img.resize((width,height),Image.ANTIALIAS)
		small_img.save(imgspath +".thumbnail."+format)
	print "done"
