In the following example, file.md uses ../img/img.png. When I move an .md file from the root of the Sphinx project

📁 folder
├─ file.md
📁 img
├─ img.png

to the root folder as follows

file.md
📁 folder
📁 img
├─ img.png

then I have to fix the path to img/img.png, because the paths are relative.

Is there a way of specifying a path that is relative to the project root, like this?

project:/folder/file.md
