Folder Structure

I am trying to understand where is the best place to learn about relative folder structures when working with Home assistant. I use Visual Studio Code to edit all YAML, including the front end.
I have a few dashboards so I decided to create a folder for each.
I am able to load them now, and it works.
I created a folder for my images used in each front end. I cannot seem to figure out how to get the images referenced in my front end.
This is the structure I have:


All my dashboards will be in my dashboards folder.
I have the following code to setup, it works.

lovelace:
  mode: yaml
  resources: !include ../dashboards/resources.yaml
  dashboards:
    lovelace-main: # Needs to contain a hyphen (-)
      mode: yaml
      filename: dashboards/manticore/ui-lovelace.yaml
      title: Manticore
      icon: mdi:tools
      show_in_sidebar: true
      require_admin: true

Right now, I have one dashboard that I am working with. All yaml files are under the folder manticore.
All resources used are in the file resources.yaml, under the same dashboard directory.
I want to put all objects under the ui-lovelace-objects folder.

My question is how do I reference from a file under manticore folder, to a file under ui-lovelace-folder.
I tried a bunch of things and the pictures will not load.

On a more general note, how does the folder reference work in Home assistant when files are not under www or the main folder?

Any pointers as to where to go to read about relative folder references?
