With this setup, no further action is needed. For example, with a file structure of:just use the image from index.bigb as:

However, if you are making a huge tutorial, which can have a huge undefined number of images (i.e. any scientific book), then you likely don't want to git track your images in the git repository.

A generally better alternative is to store images in a separate media repository, and especially store images in a separate media repository and track it as a git submodule.
