It has been shown recently~\cite{MT} shown that the values of $J_T$ and $J_L$
which appear in Eq.(2) and (5) of the above paper and which are
taken from the work of Aurenche et al\cite{pat} are too large by a factor of 4.
Correcting for this changes the Fig.~1--4 (see below).  The basic result
of the paper, that the emissions from the quark matter can outshine those
from the hadronic matter when the photon rates upto two-loop level are used,
remains valid though the range of $p_T$ over which it happens is reduced 
to $p_T <$ 0.5, 1, and 2 GeV/$c$ respecitively at SPS, RHIC, and LHC energies.
