How to save an Image or File Stream in application's settings? UWP C#

I have a List View with some ListViewItems and each one contains a TextBox and an Image.

The user can add or remove these ListViewItems, so I would like to save them in the settings each time the app is closed and load each time it is opened.

I managed to save the TextBoxes' texts in the settings and load them, but how to save and load Images / Image Sources / File Streams?

The images are created when the user chooses an image in a FileOpenPicker and then a Bitmap Image is created with a File Stream to that chosen Image, as the ListViewItem's image source.

private async void openFileInputEvent(object sender, RoutedEventArgs e)
    {
        var picker = new Windows.Storage.Pickers.FileOpenPicker();
        picker.ViewMode = Windows.Storage.Pickers.PickerViewMode.Thumbnail;
        picker.SuggestedStartLocation = Windows.Storage.Pickers.PickerLocationId.PicturesLibrary;
        picker.FileTypeFilter.Add(".jpg");
        picker.FileTypeFilter.Add(".jpeg");
        picker.FileTypeFilter.Add(".png");

        Windows.Storage.StorageFile file = await picker.PickSingleFileAsync();
        if (file != null)
        {
            using (IRandomAccessStream fileStream = await file.OpenAsync(Windows.Storage.FileAccessMode.Read))
            {
                BitmapImage tmpimg = new BitmapImage();
                await tmpimg.SetSourceAsync(fileStream);
                imglist.Add(tmpimg);
            }
        }
        else
        {
            var dialog = new MessageDialog("File not chosen", "No chosen Image");
            await dialog.ShowAsync();
            imglist.Add(new BitmapImage());
        }
    }

The bitmap images for all the ListViewItems' images are stored in a list of bitmap images (List<BitmapImage>) and they are chosen by choosing the last item on the list (imglist[imglist.Count-1])

I would like to save and load this Images / their source / file stream to their source, is there any way to do that?

I could save paths to the images, but I can't later create an Image with the path as its source, it has to be a file stream.
