Unless I personally edited an event, most of the events in AAR lack proper pictures. You don't need to see the pictures cause there aren't any.
There are event pictures but they are for DH Core. I mean bigger sized old HOI2 event pictures. These events are not stated as style = 2. I assume that this is on purpose so as to use old style event pictures ? I am currently deleting style = 2 line from events which use old HOI2 event pictures.
