I'll work on the issue template. This is the minimal folder that would reproduce the problem. The problem is still present in 1.40.1.

We've seen the problem on every windows 10 1903 computer we've tried it on. I've tried the repo on ubuntu 19.10 and it's works fine. I've tried it on macos 10.14.6 and it works.

I got the same issue on Windows 10 1903, and every time I open the preview page I got following lines in console:

[Embedded Page] Not allowed to load local resource: file:///D:/%5Copt%5CDocuments%5Cwww%5Cassets%5C2019%5CIMG_20191003_184153.jpg
  ERR Invalid regular expression: /^image\\jpeg;label:IMG_20191003_184153\.jpg;description:HEAD;size:313833;base64...

Same for me;

Windows 10 1903 / VS Code 1.40.1

I found out today that the Markdown Preview Enhanced extension still functions correctly. So if your on windows and use vscode for markdown you can install it and your images with root folder paths should function again.

@mjbvz
Still reproduce in VScode 14.0.2 on Windows 10.

As @pingu8007 mentioned, the reason is, that it can not load local images in schema such as file:///D:/....
It may be a problem with security policies.

And #85820 is a workaround to fix this bug

Same here on Linux it seems this feature is broken in all major operating systems. Absoulte path, Relative path, Absolute with file protocol to make it a valid URI, no matter what i do it doesn't load images. :(

It's strange. Did your update to latest version?
It should be fixed in last few updates and I can confirm it's works in vscode 1.41.1
