Two component advective flow (TCAF) successfully explains spectral and timingproperties of black hole candidates. We study the nature of photon trajectoriesin the vicinity of a Schwarzschild black hole and incorporate this inpredicting images of TCAF with a black hole at the Centre. We also compute theemitted spectra. We employ a Monte-Carlo simulation technique to achieve ourgoal. For accurate prediction of the image and the spectra, null trajectoriesare generated without constraining the motion to any specific plane. Red shift,bolometric flux and corresponding temperature have been calculated withappropriate relativistic consideration. The centrifugal barrier dominatedboundary layer or CENBOL near the inner region of the disk which acts as theCompton cloud is appropriately modelled as a thick accretion disk inSchwarzschild geometry for the purpose of imaging and computing spectra. Thevariations of spectra and image with physical parameters such as the accretionrate ($\dot{m}_d$) and inclination angle are presented. We show that thegravitational bending effects of photons do change the spectral shape to someextent.
