Embedding images inside a GitHub wiki (gollum) repository?

Question

The Github wikis are backed by a separate git repository then the main project repository.

This post by the Github team makes it sound like you should be able to link to

The comment from @Drew Noakes to the original question did it for me:

The syntax for the image I wanted to be displayed:

[[/images/imageName.png]]

This image was only displayed when renaming:

wikiPage.md --> wikiPage.wiki

The following folder structure was used in the wiki repository:

repository.wiki
   |--wikiPage.wiki
   |--images
        |--imageName.png       

BUT:

The syntax in .wiki differs from .md files.
