Mass Equals Frequency: Explained

[Magical]

Hey, can anyone shed any light on the significance of:
E=mc^2 and E=hv so mc^2=hv or m=(h/c^2)v (using v as frequency)

So mass = a constant (h/c^2) * frequency

What does it mean practically that a mass is equivalent to a frequency ?

Photon has no mass, E=mc^2 does not apply for photons then.
