Images from /public are not displayed in markdown

[vascotenner]

Describe the bug

I pasted an image (crtl-v) in a markdown cell. Then it asks to enter a filename, and creates the code:

![alt](public\image.png)

When I exit the cell, it stays empty, not displaying the image.

Workaround:
Replace the markdown with a python cell with:

mo.image(("public/image.png"))

Just to check, does it work if ![alt](public/image.png) ? Instead of backslash, use a slash.

[vascotenner]

![alt](public/image.png) does not work either.

Hmm, sorry about that. We'll have to investigate. If you did look at the network tab in developer console & search for image.png, do you see the file being downloaded succesfully?
