I've been to every CCon so far. It started out pretty small, but it grows every year. Last year there were quite a few people there, and it was a large and great location for a con. I mean, it's not quite as big as Anime Boston or Otakon but it's definitely a good size con, and it's a lot of fun.
As for pictures, you can check here at the CCon forums: http://www.connecticon.org/forums/showthread.php?t=556
Hope I could be of any help. ^_^
