I tried today to do an image search for <PreachingTheme = Jesus: Birth>, but got no results. I then tried {Section <PreachingTheme = Jesus: Birth>}, but that was no better.
There are plenty of such images in my libray. I can see them in the Sermon Starter Guide, and a Basic search for the Section will show results which include many images (particularly from 300 Quotations and Prayers for Christmas).
