Slide shows

I've saved my morphed images as avi files to insert them into a slide show. Is there a way to show the start of the morph for a second or two before the morphing starts.
As it is now, the viewer has barely enough time to see what is morphing, before see the result of the morph. I'm morphing baby pix into teenage photos. I'd like to be able to see the baby pict for a bit...for the 'ahhhh' reaction...before getting to the 'ooooohhhh'
Thanks.
