Does anyone know a failsafe method to put Portrait orientated slides into a presentation that is primarily landscape and retain the portrait look. This may sound stupid but the user wants to put in slides that have very long images on them, so needs this facility.

I have tried using the XP-recommended hyperlink method - as he is using Powerpoint 2002 - but whilst this works fine to take you to the portrait slides in the new presentation, when that part of the show finishes and you wish to continue in the original, the hyperlink loops into the next slide too, so that it refers back again to the portrait presentation even though there is no link in that slide.
