OT: Images not showing.

This is about Windows Live Mail on Windows 7.

A few days ago everything was working fine.  If I received something from an unsafe sender, I would get an option at the top of the screen permitting me to add the sender to the Safe Senders List.  When I did that, all the graphics would show up.

Now almost all my mail does not show graphics even when they are from safe senders.

What can I do?
