  The optical properties of Euler-Heisenberg (EH) black hole (BH) surrounded by
Cold Dark Matter (CDM) halo are investigated. By changing BH's parameters, we
found that the radius of horizon r_{h} and radius of photon sphere r_{ph} will
transparently increase as CDM halo parameters R and \rho increase. To show the
influence of CDM halo on the BH's optical characteristics, we took two sets of
R and \rho with prominent differences and plot the first four orders of images
for thin accretion disk with different angle of inclination \theta of observer.
The images with light intensity distributions using Novikov-Thorne (N-T) model
are also derived, as well as the effective potential, photon orbits.
Especially, analysis of intersection behaviors between photon trajectories with
different impact parameters and circular time-like orbits in accretion disk
will help better understand the image of thin accretion disk. Our results
showed that CDM halo will make BH become more larger and dimmer distinctly.
