[Kibana 7.2] Insert local image on a markdown visualization

[ea1987 (andrea)]

I have used another path (most recent, I guess):

<kb_home>/src/legacy/ui/public/assets/favicons/<custom_folder>

And I refer to local png in this way

http://<kb_host>:<kb_port>/ui/favicons/<custom_folder>/<custom_image>.png

Thank you for your help Nick!
Andrea
