If a bank forecloses on the home and it goes back to the bank (REO) then the bank will post the home for sale with a Real Estate Agent. Once that happens all agents servicing that jurisdiction will have access to the sale information and any photos available.
If you are looking for homes that might be facing foreclosure or a list of homes going for auction on the court house steps, you can try to check in with your local county/town/city governement court. The notices for default/delinquincy and foreclosure sale are all posted with the local court. At least that is how it happens in my neck of the woods.
