效果参见：http://blog.ixcv.com/post/360.html
部分代码：
def waterMark(im, wm):
if im.mode != 'RGBA':
im.convert('RGBA')
layer = Image.new('RGBA', im.size, (0,0,0,0))
layer.paste(wm, (im.size[0]-wm.size[0]-im.size[0]/20, im.size[1]-wm.size[1]-im.size[1]/10))
im = Image.composite(layer, im, layer)
return im
im = Image.open('./picture.jpg')
wm = Image.open('./watermark.png')
newIm = waterMark(im, wm)
newIm.save('./newPicture.jpg')
