Changing thread name

I got a problem. I called a thread in the Multimedia section "Yellow Lambo Murciélago on the road, PICS!!!!", but it should be called "Yellow Lambo Murciélago BARCHETTA on the road, PICS!!!!". I edited it, and now if you open the thread, the good title is above the first post. But in the Multimedia section it still says "Yellow Lambo Murciélago on the road, PICS!!!!" without "Barchetta".
Not to long ago there where a lot of pics of a normal yellow Murciélago on the road. So I guess most people guess the thread contains those pictures, but it contains new pictures of the new Barchetta. So could someone (a moderator) please change it?
