We present results and first epoch parsec-scale images from a monitoring program on five γ–ray loud blazars selected on the basis of their total flux density variability. We observed 0048−097, 0235+164, 0954+658, 1510−089 and 1749+096 with the Very Long Baseline Array simultaneously at 8.4 GHz and 22 GHz. Comparison between our high quality images and previous results from the literature sugges...
