The trick is knowing that the pedals screw in if you pedal the cranks backwards. They screw out if you pedal the cranks forwards. Knowing that, you can either look closely at the threads or just use trial and error.

That pedal appears to have left hand threads , thus it will go on the left side of the bike.
