Add an image to Dashboard / Course home page?

Hi, thanks for the quick reply!

I’ve found those settings but where would an image go?

Perhaps these images will explain more. This is what Im trying to do…(note I have hidden text due to NDA but there is a title and body text in there)

However this is on a page. There is a defined block in the page builder:

Is the same possible on a Topic and the Main course menu (first in the Course builder chart)? At the minute, no matter what I do I only get a solid colour.
