				<para>
    This is the second of two papers presenting the Second Caltech-
    Jodrell Bank VLBI survey (CJ2). The CJ2 sample consists of 193 flat-
    and gigahertz-peaked-spectrum sources selected at 4850 MHz. In this
    paper we present images of the remaining 102 sources with ~1 mas
    resolution, obtained using VLBI snapshot observations at 4992 MHz with
    a global array. We also present integrated radio spectra for the
    entire CJ2 sample.</para></description>
