In this case, Mary's solution is the only solution. Copy/paste and change out the images. In some styles, the image fills in some of the others automatically. Love that. But in others they don't.
In other cases, depending on the style, it works to copy settings to other slides instead (and you could do that to a number of them at the same time) but only if there is one image, one layer and certain settings applied to that image. Unfortunately, key frames don't copy if there are more key frames in one slide and less or more in others.
I was just proposing another way of copying a "style" of sorts but only within certain circumstances and those are probably the more simple styles. What you would be doing isn't really copying a style but just copying settings to other slides.
There is a feature to "combine slides" but I haven't used that in a show other than experimenting with it a few times.
