Take a look at AlbumManager::refresh.
It's called from dio.cpp, Watch::slotDone, which is called after DIO::scan, 
which is called from AlbumManager::slotDirty, which is called from the

SELECT count(*) FROM Images  WHERE dirid=%1
(see albumdb.cpp for many other SQL statements)
It'd need to be passed through AlbumManager.
