Force PowerPoint to Detect Picture Changes

Hi

Powerpoint can link to inserted files. And you can have a continuously slide
show. So far so good. However if you change the contents of a picture or even
delete it, Powerpoint will not pick this up. You need to stop it and restart.
We have need for a continuous powerpoint where some of the pictures change
overtime.

= Is there any way to force Powerpoint to re-fresh its picture cache on
file changes ?

Thanks

tried in Powerpoint 2003 & 2007, same result.

I seem to recall that there are some commercial solutions to this. I'm
thinking that the alternative is a VBA solution. It's not too hard to
have a button on the first slide that automatically sets the slides in
motion and every so often reinserts the picture(s). I don't think it
would be too a lot of code to do this.
