This is a question that has already come up in the forum several times, so I'm posting the tutorial here too, in the hope that it would be easier to find.
Is there a way, to pause the motion in a slide style, so that the pictures can be viewed?
For example, the slide style "display of nine expanding"...after all the photos have expanded, I would like for it to pause for a few seconds before going into the transition.
If you take a look at the slide styles that are available in Gold, you will notice that some have a duplicate called "still".
You can use these still styles to achieve your pause. Just insert in them the very same pictures that you inserted in the style with the motion, and add a 0 seconds transition between these two styles. Make this slide for as long as you need your pause.
Another, much simpler alternative, is to insert a new empty slide after the one with the motion. Change the transition time between these two slides to 0 seconds.
In your slide with the motion, use the function "Copy End to Next Slide (All Layers). (the icon on the side)
The last position of all your layers will be copied to the empty slide that you created before. Change the duration of this slide for as long as you need your pause.
Now, you have a chain of two slides - one with motion and one static (still). Use a normal transition only after the static slide, and you will see that your pictures are displayed for as long as you need.
