AMPV Is it possible to add new images in the Slideshow without a reload of the website?
I add from a Camera over ftp some new images to the gallery. They should appear automatically in the slideshow. Because the slideshow runs on a big screen and nobody has the time to always reload it.
First of all, when you say "add new images in the Slideshow", you mean images uploaded via FTP to automatically inject themselves into the slideshow that the visitor is currently navigating after clicking to zoom an image? Sorry, that definitely won't work, because the slideshow is created dynamically when the visitor clicks an image, based on sort order and filters. It can't start update itself on the fly from data that was uploaded by FTP.
If you ask me if it's possible to update the current folder, even this is difficult. Files Gallery can't achieve anything like this without reloading the dir at certain intervals. There is no "push" mechanism that can push your FTP changes into the browser. So ultimately, this would depend on a feature to "reload current page at certain intervals". This could be done invisibly, but it still needs to check if the folder was updated and then reload the items if necessary.
There are some related feature javascript_cache
and localStorage_cache
in javascript config, but these options only make sure the folder will reload when navigating to each folder from the menu.
AMPV If the auto update is not possible (till tomorrow). Is it possible to reload a website and autoplay the slideshow?
You can of course "reload" the website directly from browser by clicking the browser reload button, or keyboard shortcut for reload. I don't see how this should be done automatically from Files Gallery ... When is it supposed to trigger a reload? You could add some script to force reload every x minutes, although this doesn't seem very practical.
The slideshow itself will automatically open for an image when the url contains a link to an image, for example:
https://demo.files.gallery/?balloons#pid=aaron-burden-GFpxQ2ZyNc0-unsplash.jpg
AMPV Is there a possibility to shuffle the slideshow play?
There is already a shuffle sort option. As long as this option is selected, it will always load the folder in shuffled order. Or you can re-click the shuffle button to re-shuffle. You cannot shuffle items directly inside the slideshow. Slideshow will always inherit the order of the items in the layout, which of course are already shuffled.

Sorry, but I don't think Files Gallery can easily achieve what you are asking.
