Embedding Images into shinytree


I am new to R studio and shiny so I was wondering if I could get some clarification.
I am creating a shinytree using a RMD file containing yaml. I would like to embed images within the tree but am unable to do so after searching for hours on stackoverflow and github.

Here I have attached an image of a sample tree and where I would like the image to be placed (either directly in that spot or in a window below). The yaml rmd used for the text of the tree is also in this image:

Any help would be greatly appreciated!

Thank you.
