If I have a slide show with say 300 slides, is there a way to insert a blank (all black) slide in between each slide in the current presentation without doing it manually? I need to insert the blank slides after I have loaded the 300 individual image.

Do I need a script or macro to do this? or can it be done through the menus or interface?

I have very large slide shows and need to insert black between each slide, thanks.
