add fullwidth image on every page within any parent

hi – thanks for all your past support.
We have an Enfold site in development with a couple hundred pages. I’d like to place a thin fullwidth image beneath the title / breadcrumbs bar without having to place the image on each page by hand. The image would change depending upon which parent the page has. For example: all pages with the parent “baseball” would have the same image, and all with the parent “football” would have another etc etc.

do you know of a way to do this?

Thank you!
