Prior to upgrading to 4.0.2, the photos uploaded by members in my forum's social groups were displayed at the top of the group discussion page, in (if I recall correctly) a condensed 2 row x 4 column format. After the upgrade, however, each of the eight latest photos are shown in what appears to be a single column with a massive amount of blank space below them, as seen in the screenshot (the amount of blank space actually extends down another half screen before the next photo appears).
