Slide show autorotate uses the previous image

[smurfix]

In a slide show with autorotate turned on and a mixed bag of portrait and landscape images, autorotate uses the previous picture's proportions for setting the new picture's rotation.

Needless to say that that's not what the user intends to happen.
