Hey how do i put a picture of my car after eveytime i post a reply...? does anyone know?! thanks!

I think your referring to putting a picture in a signature, like my pic of the E60 M5. If so...

1) upload a picture into the AF Gallery
2) copy the link provided to you
3) go to your "User CP" and go to Signature controls
4) type (value) where "(value)" is the link from your pic
