How much space does a photon take up?

I always imagine them being tiny but then how does a long wavelength differ to a shorter one?

Also how many photons could fit in a given space?

There are two possible answers:

1. It has zero volume

2. The question of a photon's volume has no physical meaning.

I tend towards the latter. It doesn't have a volume any more than it has a smell, a star sign or a favourite Spice Girl.
