THere are lots of ways to do this, but the easiest (IMO) is to use your grid within your custom shapes tool and place it over your photo. Once you're done, you can just delete it. Maybe someone else will have another suggestion too!

If you make your rulers visible, you can drag two guides from the ruler to where your lines would be to divide the layout, and then do it in the opposite direction. That's how I would do it. Nothing to delete.
