How to delete inserted elevation/section image box?

I am trying to insert JUST the cross section (or elevation) image as viewed as renedered-outline into my floor plan tab.

The image comes with a LARGE green-box surrounding the cross section (solid white) which wipes out any/all other images below it.

Can this green-box be deleted or trimmed such that only the house is visible and no longer wipes out other images nearby?
