After reading this question about why Sanji's bounty poster is drawn, not his real picture. I was just thinking about the bounty posters itself. I know that aside from Luffy, the rest of the crew's bounty posters are taken after Ennies Lobby arc.
But how about their bounty hunters picture after time skip? I know it's probably when they are in dressrosa, but if I saw Sanji's and Chopper's posters, it's seems that their posters are taken in Sabaody Island. And also Franky's bounty poster taken when he's in Punk Hazard or Fishman Island because it's shown his Franky Shogun, not his true face. He only used Franky Shogun at Punk Hazard when battle with Buffallo and Baby 5 and when he's battle Fishman Pirate at Fishman Island.
So, I want to know where and when Mugiwara Crew's new bounty posters were taken?
