  We use an event-by-event hydrodynamical description of the heavy-ion
collision process with Glauber initial conditions to calculate the thermal
emission of photons. The photon rates in the hadronic phase follow from a
spectral function approach and a density expansion, while in the partonic phase
they follow from the AMY perturbative rates. The calculated photon elliptic
flows are lower than those reported recently by both the ALICE and PHENIX
collaborations.
