We determine the radiative decay amplitudes for decay into D^* and D γ, or D^*s and Ds γ of some of the charmonium like states classified as X,Y,Z resonances, plus some other hidden charm states which are dynamically generated from the interaction of vector mesons with charm. The mass distributions as a function of the D γ or Ds γ invariant mass show a peculiar behavior as a consequence of the D^* D^* nature of these states. The experimental search of these magnitudes can shed light on the nature of these states.
