Well, "freezing" light - or "stopping" light - is a bit of a misnomer; technically it seems as if they're preserving, and then recovering, the state of a given set of photons through the medium of a particular crystal structure.  They don't actually make a photon come to a screeching halt and sit there as if it were a car at a traffic light.

Understanding how those scientists achieved that bit of wizardry was about as easy as understanding the Planck constant.

So, it's kind of like taking a "snapshot" of it?

Great metaphor, cat.  Think data storage.  LOTS of data.

In a way, that's probably a way to think about it.  The difference from a photograph is that the "frozen" light can be recovered from the substrate.  Maybe it's like taking a mold of the light wave and then using the mold to generate a new light wave with the same state characteristics as the original light wave.
