I see that someone said the photos are classified.
That's not quite correct. Colin Powell showed them to the UN Security Council in the fall of 2002 and they were viewed on live television.
That doesn't mean that they aren't still classified.
In many cases, the classification depends on the resolution of the photograph. A low resolution version might not be classified, but a high resolution version will almost certainly be, if only for the fact that the degree of resolution reveals as much about our capabilities as they do about the actual subject of the photo.
Pictures of trucks don't mean much unless you also have pictures of identifiable material being loaded into the trucks or being unloaded at the destination. In the months leading up to the invasion, you can be darn well sure we were doing every possible form of satellite surveillance of Iraq. The pictures we would really want to see almost certainly exist and are guaranteed to be classified. Powell would have never had these photos at the UN.
Having said all that, always remember-this is the government. Logic need not apply.
I think I've seen some of them (screen captures maybe?) on some threads on FR, too. I know I've seen them.
