fromResource 
  Creates a new GtkImage displaying the resource file @resource_path.
If the file isn’t found or can’t be loaded, the resulting GtkImage will display a “broken image” icon. This function never returns null, it always returns a valid GtkImage widget.
If you need to detect failures to load the file, use ctor@GdkPixbuf.Pixbuf.new_from_file to load the file yourself, then create the GtkImage from the pixbuf.
The storage type (see method@Gtk.Image.get_storage_type) of the returned image is not defined, it will be whatever is appropriate for displaying the file.
Return
a new GtkImage
Parameters
resourcePath
