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

None of answers seem to work when adding an image in readme.md. I've got a solution though:

If the URL of the image is:

https://github.com/Username/Repository-Name/blob/master/Directory-Inside-Repository/image.png

Replacing blob with raw gives you the URL of the raw image:

https://github.com/Username/Repository-Name/raw/master/Directory-Inside-Repository/image.png

Now, you'd embed the image using normal markdown:

![Image Alt](https://github.com/Username/Repository-Name/raw/master/Directory-Inside-Repository/image.png)

UPDATE: As of now, GitHub also serves raw images from a different sub-domain raw.github.com. So, you can also use:

https://raw.github.com/Username/Repository-Name/master/Directory-Inside-Repository/image.png
