How to add path of the image folder in this python code?

Here is my code that allows my bot to send random pictures from any folder where the python code is situated.

elif command == 'Hello':
    pic_list = glob('*.jpg')
    get_random_pic = random.choice(pic_list)
    with open(get_random_pic, 'rb') as photo:
       telegram_bot.sendPhoto (chat_id, photo)

But the problem of this code is, the code file must be situated in the image folder instead of outside. How can I add the folder location of images in this code?
