### Solution for the "window - not responding" problem with cv2.imshow()
```python
pip install a-cv2-imshow-thread
```
```python
Usage:
import glob
import os
from a_cv2_imshow_thread import add_imshow_thread_to_cv2
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]
You can pass a list of images or a single image
window_name: str
Window title
(default = "")
sleep_time: Union[float, int, None] = None
Useful if you have an image sequence.
If you pass None, you will have to press the quit_key to continue
(default = None)
quit_key: str = "q"
key to close the window
Returns:
None
```
