  Two component advective flow (TCAF) successfully explains spectral and timing
properties of black hole candidates. We study the nature of photon trajectories
in the vicinity of a Schwarzschild black hole and incorporate this in
predicting images of TCAF with a black hole at the Centre. We also compute the
emitted spectra. We employ a Monte-Carlo simulation technique to achieve our
goal. For accurate prediction of the image and the spectra, null trajectories
are generated without constraining the motion to any specific plane. Red shift,
bolometric flux and corresponding temperature have been calculated with
appropriate relativistic consideration. The centrifugal barrier dominated
boundary layer or CENBOL near the inner region of the disk which acts as the
Compton cloud is appropriately modelled as a thick accretion disk in
Schwarzschild geometry for the purpose of imaging and computing spectra. The
variations of spectra and image with physical parameters such as the accretion
rate ($\dot{m}_d$) and inclination angle are presented. We show that the
gravitational bending effects of photons do change the spectral shape to some
extent.
