据我所知，我认为你只是想使用python一次性地水平或垂直翻转它们（图像），并以相同的名称保存它们--如果是这样的话，你可以通过

import os # just for getting name from file path
from glob import glob # read file in directories
from PIL import Image, ImageOps # reading & processing image
from tqdm import tqdm # loading bar (unnecessary but it help visualizing waiting time when process high amount of files)

horizon_or_vertical = 'horizon' # option to choose between horizon/vertical flip
for file_path in tqdm(glob('./folder/*.jpeg')): # using *.jpeg exclude other format Note: that tqdm can be removed
    file_name, ext = os.path.splitext(file_path) # get old file name by split the path
    with Image.open(file_path) as image: # read image
        if horizon_or_vertical == 'horizon':
            translated_image = ImageOps.mirror(image) # horizon flip
        else:
            translated_image = ImageOps.flip(image) # vertical flip

        image.save(file_name, "JPEG") # save in JPEG format with the same name in the same folder
