Secondary {gamma}-rays from intergalactic cascades may contribute to
observable spectra of blazars, also modifying observable angular and temporal
distributions. In this paper we briefly review basic features of intergalactic
electromagnetic cascade physics, suggest a new approximation for {gamma}-ray
mean free path, consider angular patterns of magnetically broadened cascade
emission, and present an example of a fit to the observable blazar spectrum.
