Some of the pictures you see here are focused on Owen and you won't see them in the finished film. The one where Owen is standing must be some kind of alternate take or extended version of the scene where Anakin learns of Shmi's fate. In the finished film, Owen never even gets up from his chair. He originally appeared in the following scene offering Anakin his speeder, but he was ultimately split-screened out of the shot.
Let me explain why I'm putting the picture of Padmé in this section. I really can't say for sure and I really don't have any hard evidence, but I believe this photo to be from the scene on Tatooine where Anakin learns about his mother, the scene we're discussing on this page. In the book, Mythmaking, it's placed in the chapter dealing with pick-up shooting, long after principal photography was wrapped. My only educated guess here is that someone decided another scene of Padmé in the Lars dining area was needed - probably the part where she sits in the chair, since there's a blue chair there under her. So there's my best guess, folks.
The picture with Anakin, Owen, and Cliegg is from the German Lucasfilm magazine, the solo shots of Owen and Anakin alone are from Starwars.com, and the Padmé picture comes from the book Mythmaking.
