Lantern festival gathering

Every year, I'll normally get together with my college friends during the mid-autumn festival. It has been an annual event for 4 years. We'll get together at the Bukit Jalil park. That's the place where we'll eat, chat and light up lanterns.

I remember having pictures taken every year at the same place and spot. Can you identify which pictures were taken in year 2003, 2004, 2005 and 2006?
