Image path doesn't work properly on Windows 10

[SuschNL]

When inserting an image into a Markdown document at a relative path, using a forward slash doesn't work (at least on Win10). For example, this renders a broken image: ![MyTestImage](../images/MyTestImage.PNG)

Where-as this renders correctly: ![MyTestImage](..\images/MyTestImage.PNG)

I need to utilize forward slashes only, as these documents are being pushed to a GitLab repo and being rendered with MkDocs to Gitlab Pages.
