I like what jester said, how you have a gang picture inventory.
I also like what classic does, having it reviewed and a cool-down time.
I don't like the Ec for the gang leader. People could abuse this, how, idk.
I like the in-game drawing of gang pictures, only there will be some immature people drawing inappropriate things, so maybe have a review system for this too.

Or, just simply remove the gang picture system, seeing as people are generally very stupid in the majority and minority. Anyway you go, there are still going to be immature people who find creative ways to be inappropriate. And I know, I know. This idea could create riots and stuff short term, but lasting effects could be a cleaner, more mature era for everyone.
