![title](image.png)

And the image is part of the repository.

Steps to reproduce

Create an IPython notebook, add image and add both of them in a GitLab repository and push. Viewing notebook directly will show you image but images won't render in 'Display Notebook' section of GitLab.

Example Project

https://gitlab.com/deepeshreja/test

What is the current bug behavior?

https://gitlab.com/deepeshreja/test/blob/master/image.ipynb doesn't image in 'Display Notebook' view but the actual Notebook shows that image.

What is the expected correct behavior?

Image should be displayed.
