Experimental data for hadron radial and elliptic flow are used to investigatetheir influence on the shape of the thermal photon spectrum at RHIC. Leavingalone the actual mechanism of photon production and its time evolution, weconcentrate on the spectrum shape. Radial and longitudinal flow of the bulk canchange significantly the observed photon energy spectrum via the DopplerEffect. Experimental thermal photon data are described by local frametemperature parameter which depends on the assumption of longitudinal andradial flow. From the observed hadron elliptic flow we estimate the modulationof radial flow parameter versus the angle relative to the reaction plane. Basedon this we calculate elliptic flow parameter for thermal photons, which wasfound to be very close to that for hadrons. Considering very similar amplitudefor hadron elliptic flow at LHC and RHIC, we demonstrate that thermal photonsat LHC should show large elliptic flow as well. All of these considerations arealso valid for the low invariant mass dilepton pairs.
