As part of an investigation on what effect galaxy interactions have on the z-structure of the disks of involved galaxies, we present here new photometric data in the B, V, I passbands for a sample of 24 interacting systems and 7 non-interacting galaxies. Isophotes, total magnitudes and colours of all sample galaxies (67) are determined. Our estimates and the comparison with the published results show that the accuracy of our photometry is about 0.15 mag.
