Locally saved images not loading in panel markdown when using show()

Panel
1

Hi There,
I am able to create a pane using an image from the web but when I try to use a locally stored image it only shows a fractured image icon. For the minimal working example below you’ll need to place a copy of the tux.png file in the folder where the code is running from.
Any guidance and assistance is most welcome thanks

import panel as pn
pn.extension()

md=pn.pane.Markdown("""

### Image From web

### Image From Local

![alt text](tux.png)

""", width=500)

md.show()
