I've got a picture that's 400% larger than the slide extents.

I'm trying to use the Shrink animation so that the picture will shrink
to fit the slide extent. From a viewer's point of view, this will be
like starting in on a close-up and "pulling out" to reveal the whole
picture.

The problem is, when you try this the shrink animation doesn't take
the whole picture with it. Instead, it seems to take a weird portrait-
orientated section not a lot wider than the original slide. Therefore,
it technically works except it's missing large bits down either side.

Anyone know why this is, and is there an easy workaround?

I don't want the full image to appear even for a brief second, so the
only workaround I've got so far is a very complicated one involving
disappearing the image, zooming it to 400% in 0.1 seconds, then making
it appear, then shrinking it back slowly again. It works, but it's
very clunky and slow to program in.

I'm using PowerPoint 2007.

Thanks in advance,

Steve
