As far as webpage, go somewhere free that hosts pics like Cardomain or Imagestation. There are others, but these two seem to be the most popular around here.
Even MY Chevy Truck (another truck site) has a nice gallery option IMO.
Now to the sig.
Get some pictures up and someone can create you one, or you can create yourself one. But you do need a place like Imagestation to host the sig so It can be displayed here on GMFS.
Hopefully that answers your question for the most part.
