Roger, I understand your frustration with older auction info and pictures that are no longer available. The issue here is copyright infringement. Copying someone else's pictures and words and posting them somewhere else can be a legal problem that could make that person vulnerable to a copyright lawsuit. The likelihood is not great, but it is possible.
A safe alternative is to pay close attention to these auctions and the forum discussions about them. Print the auction pages and file them for future reference about that seller and about similar items.
