Joker, one thing I just noticed. I think Stephen Jackson has cornrows in that pic. He doesn't have them anymore, cut them off a few months ago. You might want to replace the pic with the crew cut he has now.
Theres no point in asking for things like that. When a player changes hairstyle, the NBA doesn't all of a sudden grab some photographers and head down to his house for a quick photo shoot so people can put him in the game. They get their photos taken at the start of the season and (most of the time) when they are traded.
Since NBA media central (where you obtain these by saying you work for the media) doesn't update their pictures very often, if ever, after trades you have to use the current picture and switch the jerseys. Those pics aren't exactly real, for example Dijon Thompson had no picture available, so I had to put his face in Eddie House's head. The rest of the pictures are the originals from seasons start (or earlier) with the switched jerseys, so if the player has changed his appearance since the trade, it doesn't matter because that won't be reflected in the picture.
Unless you want to spend a couple hours on each player editing the picture in photoshop to change the hairstyle, these [unnecessary] changes won't be happening (barring new pictures are released, even though we have something perfectly fine at the moment).
