How do you send a mugshot or smugshot online in burnout paradise for ps3?

May be...

you can get a trophy for doing it but i dont know how.how do you?

Simple, you connect your Playstation Eye camera or any other USB camera, you sit it on your screen or towards the wall (if you don't want people to see you) and leave it there. Once you do that go online, either take down someone or get taken out you either receive it or send it! Hope I helped!
