i like to change the path in with the picture command is starting to a spezific folder at startup. i already tried this:

var settings = GetPluginSettings(
                RhinoApp.CurrentRhinoId,
                false);

var directories = settings
    .GetChild("Options")
    .GetChild("DefaultFileDialogDirectories");

directories.SetString(
    "BitmapDirectory",
    notesFolder);

but it looks like this is not the correct setting.
