Who's site is that? Dale's? Dan's? Other?
That would be a shame to loose all that info. It is very possible the Internet Archive Project aka. "The Wayback Machine" has page copies saved there.
Anymore, I would keep things in memory, disk, flashstick or whatever. Plus mulitple cloud storages. Why? Because no cloud has saved everything I put there, and free photo sites can restrict your recovery of photos any old time they feel it. E.g. Unrestricted access to your account Photobucket went from free to $300 a year. Ive recovered 80% of what is left (many vanished), but that is since Dec of 16, a slow process at best, and many failures because they disconnect you.
