Tag your conference pictures with europython2009 so that they show up in the EuroPython 2009 stream.
You might also want to tag pictures with europython. Avoid ep tags (like ep2009) since they are a bit too general and your pictures will end up getting mixed in with all sorts of other random stuff.
See the pictures from EuroPython 2008.
