"Problem
You open a presentation in PowerPoint 2002 or 2003 and one or more images
appears upside down.
No matter what anyone may tell you, it's not because you've opened an
Australian presentation in your US English PowerPoint.
Solution
This only seems to happen to PowerPoint presentations that have been created
in earlier versions of PPT and opened in 2002/2003.

PowerPoint MVP Shyam Pillai has written a free Unflip add-in that'll fix the
problem."
