We have observed a sample of 15 bright active galactic nuclei (AGN) three times during 1992-1996 using the global 22 GHz VLBI network. The sample consists of all sources in the complete 2 Jy catalog of Valtaoja et al. that were not observed at 22 GHz VLBI before the first epoch. We will present submilliarcsecond resolution VLBI images of these sources with description of the observations and data analysis techniques. Part II of this paper will contain a detailed analysis of the images.
