  In this paper, we aim to investigate various physical properties and
characteristics of radiation emerging from the surface of accretion disks, in a
rotating traversable axially symmetric wormhole spacetime of the Teo class. We
have studied the marginally stable orbits and accretion efficiency graphically,
corresponding to different values of dimensionless spin parameter $J/M^2$
ranging from 0.2 to 1.5 and some values of the throat radius $r_0$, in
comparison to the Kerr black hole with the same parameter values, and also
tabulated the results. The energy flux radiated by the accretion disk $F(r)$,
the temperature distribution $T(r)$ and the emission spectra $\nu L(\nu)$ is
plotted, corresponding to varying values of the dimensionless spin parameter
$J/M^2$ and throat radius $r_0$. Also, the critical frequency at which the
luminosity attains its maximum value, for various values of the angular
momentum of the wormhole $J/M^2$ and $r_0$ is tabulated. Lastly, we have
employed ray-tracing technique, to produce the intensity map of the image of an
accretion disk, as observed by an asymptotic observer, under two conditions:
firstly when the disk is on the same side as the observer and we have also
compared those with the images of an accretion disk in case of Kerr black hole
with same parameters. Secondly, the images have been provided when the disk and
observer are on opposite sides of the throat. This study may help to detect and
distinguish wormhole geometries from other compact objects.
