All current images aren't changing. The most recent category "Outfits" was voted upon. Only so many I can change. For maybe a different category we can add new badges. The next one will not be skins however.
Well Renegade Raider is considered one of the best, if not the best skin on Fortnite. If someone reaches higher then Renegade, I might just drag everything up by one. That person will still have Renegade. Not sure yet though. Wouldnt put any common skin up there though.
