You need to upload the picture on imageshack.us for instance, the you copy their code in the signature area wich is slighty above
BTW, for the vids, you will need somebody able to rip them, no idea if you know somebody.. if you will manage to put the vids in the PC they would be pretty big since a 60 min VHS would end up in something around 300 or 400 MB for good quality, but we could sort something out for the hosting if your car will be featured
