Here's a link to the thread you mention:

What's interesting - and may be what tez was referencing - is that if you click on the jpg links Greenhalgh provides, you get (or, I got) an error message: "The page cannot be found." Which means the pics are not at the location the browser has been told, and is an indication they have been moved on or removed from the server.
Is it possible tez thinks this means the BA has deleted them?
