    import os

    from a_cv2_imshow_thread import add_imshow_thread_to_cv2 #if you saved this file as z_imshow.py

    add_imshow_thread_to_cv2() #monkey patching

    import cv2

    image_background_folder=r'C:\yolovtest\backgroundimages'

    pics=[cv2.imread(x) for x in glob.glob(f'{image_background_folder}{os.sep}*.png')]

    cv2.imshow_thread( image=pics[0], window_name='screen1',sleep_time=None, quit_key='q') #single picture

    cv2.imshow_thread( image=pics, window_name='screen1',sleep_time=.2, quit_key='e') #sequence of pics like a video clip



        Parameters:

            image: Union[list, np.ndarray]
