In braneworld cosmological models, the geometries corresponding to black holes are different than in the standard scenario. As a consequence, the optical properties of black holes change. In this talk, braneworld black holes are analyzed as gravitational lenses and the feasibility of observation of the images is discussed. For rotating braneworld black holes, the deformation of the shadow is also considered. The size and the shape of the shadow depend on the mass and the angular momentum, and they can also depend on other parameters specific of the particular model adopted.
