This are some logos I made for the games. I took the logos from the Scores & Schedules page in NBA.com: http://www.nba.com/gameline/20120410/

solovoy's portraits v6
Added Alan Anderson and James Singleton. Changed some pictures from old releases for better quality pics. TURK Script included in the file compatible with LG and Kova last rosters. The Turk could work with another edited roster, but I can't be sure that everything is going to work. Added 41 Draft Prospecs. The list with the names and IDs here: http://pastebin.com/KjtLBsTW

Compatible with Albys' RR4 and Official Rosters without using the TURK Script.
I also added the portraits of new coach Canales (PortrID: 5191). You need a paid version of Reditor to edit the PortrID of the coachs.
This only contains Portrait.iff and Portrait.cdf files. Before copy this to the NBA 2K12 folder, delete Portrait_hi.iff and Portrait_hi.cdf files (make a backup first) and then copy and replace the other two files.
Note: I always try to find the best picture in position and size; but with some legend's it was almost impossible to find a good picture or even a picture. I made my best, I'm pretty happy with some of them but with others is the only I could do.
White Jerseys Edition
All players with White/Grey Jerseys. Changed all the coloured headbands for white ones. Perfect for Association Mode.

Team Jerseys Edition
I added an effect to the pictures. If you don't like it, I'm gonna update a version without that effect. Just give a try. Perfect por NBA Today Mode. Some players may not have their team jerseys, but that's only because the roster isn't updated.
