While I am grateful for the work of Cloud Vision and the ability to design to a multitude of items - certificates, ID cards, letters to parents, etc - there is little variety in what I need for the yearbook. I need the photo and its caption name pushed to the #Lon19 template. Nothing else.
And, thanks to a face-to-face workshop with Alice Keeler yesterday, I now know how to code my own mail merge for SlidesYearbook. You can learn more about that class by reading Streamlining SlidesYearbook with Code.
