  We investigate the impact of the recently published ISRF model of the Milky
Way by Popescu et al. on the CR electrons and positrons in the context of
cosmic-ray transport modelling. We also study predictions for diffuse Galactic
gamma radiation and underline the importance of the increased ISRF
intensities.We use the PICARD code for solving the CR transport equation to
obtain predictions based on Galactic cosmic-ray electron fluxes. We show that
the new ISRF yields gamma-ray intensity increases, most particular at the
Galactic Center and in the Galactic Plane. The impact is largest at energies
around 220 GeV.
