How can I refresh a slideshow when folder content changes?

I use a Raspberry Pi to show a slideshow of pictures stored in a folder. If I add pictures to the folder while the slideshow is running, the new pictures are not added to the slideshow.

How can I achieve this without interrupting the slideshow?

Add an autostart script to Kodi. It will run the slideshow automatically when Kodi starts and refresh the slideshow if the content of the folder changes:

# ~/.kodi/userdata/autoexec.py
# On Kodi startup, automatically start a Slideshow
# Refresh the slideshow if the content of the folder has been updated

import xbmc
from os import listdir
from time import sleep

xbmc.log('[refresh-slideshow] Starting')

monitor = xbmc.Monitor()
picfolder = "/PATH/TO/FOLDER"

# Generate list of images and start slideshow
l1 = listdir(picfolder)
xbmc.executebuiltin('SlideShow(%s)' %(picfolder))
xbmc.log('[refresh-slideshow] Slideshow started, monitoring')

# Wait for slideshow to start
sleep(5)

# Monitor during slideshow
while not monitor.abortRequested():
    # If slideshow is still running, compare directory contents
    if xbmc.getCondVisibility('Window.IsActive(slideshow)'):
        l2 = listdir(picfolder)
        # Restart slideshow if directory contents have changed
        if l1 != l2:
            xbmc.log('[refresh-slideshow] Folder contents changed, restarting slideshow')
            xbmc.executebuiltin('SlideShow(%s)' %(picfolder))
            l1 = l2
    # If slideshow is no longer running (user has exited), exit script
    else:
        break

    # Wait for 60 seconds, break if abort is requested
    if monitor.waitForAbort(60):
        break

xbmc.log('[refresh-slideshow] Finished, exiting')

Convert your screensaver script to class based if it is not. Create another class to update images using threading:

import xbmc, xbmcgui, threading

class MyMonitor(xbmc.Monitor):
    def __init__(self, *args, **kwargs):
    self.action = kwargs['action']
    # do some action here.......

    def onScreensaverDeactivated(self):
        self.action()

class ImgVideoUpdate(threading.Thread):
    def __init__(self, *args, **kwargs):
        self._get_items = kwargs['data']
        threading.Thread.__init__(self)
        self.stop = False
        self.check_update = 50  # set thread to update images(in seconds)
        self.Monitor = MyMonitor(action=self._exit)

    def run(self):
        while (not self.Monitor.abortRequested()) and (not self.stop):
            count = 0
            while count != self.check_update:  # check for new images every 50seconds
                xbmc.sleep(200)
                count += 1
                if self.Monitor.abortRequested() or self.stop:
                    return
            self._get_items()

Now initialize ImgVideoUpdate from the ScreensaverWindow class from where the screensaver is running:

class ScreensaverWindow(xbmcgui.WindowXMLDialog):
    def onInit(self):
        xbmcgui.WindowXML.onInit(self)
        self.volumeCtrl = None
        # Get the videos to use as a screensaver
        playlist = self.imagelist()
        thread = ImgVideoUpdate(data=self.imagelist)
        thread.start()
