• VS Code version: Code 1.22.2 (3aeede7, 2018-04-12T16:38:45.278Z)
• OS version: Windows_NT x64 10.0.16299

I tried:

• searching through the existing open issues but could not find a matching one
• specifying the issue below as specific as I could

Image preview test

Steps to reproduce:

1. Download https://via.placeholder.com/350x150.png to a local directory
2. Save this text in the same directory as test.md (see permutations below)
3. Open test.md in Visual Studio Code 1.22 or higher (tested on Windows 10 Pro x64 or Mac High Sierra)
4. Enable the markdown preview window

The "Local image" preview fails to render on Windows when both files are in the same directory on:

• a \\ based network share
• the root of a drive

The "Local image" preview succeeds on Windows when the files are on a regular drive letter in a subdirectory (even when the drive is pointing to a network share).

The "URL image" preview always succeeds (when there is an active internet connection)

URL image

Local image

The "Local image" fails when the files are stored at:

• \\tsclient\tmp
• \\tsclient\tmp\directory
• \\localhost\c$\ProgramData\Temp
• T:\ after a net use T: \\tsclient\tmp
• C:\
• a Mac

The "Local image" succeeds when the files are stored at:

• C:\ProgramData\Temp
• X:\ProgramData\Temp after a net use X: \\localhost\C$
• T:\directory after a net use T: \\tsclient\tmp
