      and another test, open a browser on mm, then use the full file url to the new image file

      file:///home/pi/MagicMirror/modules/MMM-ImageSlideshow/…

      and see if the pic opens

        Clicking makes the capture and overwrite the file successful in the process where the magic mirror is run. But it doesn’t appear on the screen.
        When the magic mirror is turned off and restarted, a new image will appear successfully.

        I think the code is working properly, but the MMM-imageSlideshow module is not being renewed.

              @sdetweil When I click Refresh in Chrome, a picture that has been successfully changed appears.

              Is there any way to restart a specific module?

                @emrhssla i think this is a caching problem… the ‘file’ was already loaded…

                see this discussion about adding a string to the end of the image filename to make it ‘unique’
                thus not reading from cache

                https://stackoverflow.com/questions/728616/disable-cache-for-some-images

                however, this will add a new image to be cached… eventually growing maybe beyond memory limits…
                another way is to disable caching in electron

                in MagicMirror/js/electron.js
                add this line

                function createWindow() {
                    app.commandLine.appendSwitch('--disable-http-cache');  //< -------- added
                	var electronOptionsDefaults = {
