Nathan,
If the Pastors sermons are in PowerPoint, using the "Import SlideShow" option under the "Insert Elements" will convert the PowerPoint into a multi page image cue without the need for creating a new page for each image.
As far as doing the same with multiple images, since this is working as designed by adding new pages, it is not high priority. However, it is already on the Feature Request list and is under consideration. With the ability for multiple "Objects" (images) on one page, there is some complicated logic that needs to be worked out before we can make this happen.
