+To find the image dependency, you will need to do a bit of detective work, finding the image in a registry, and inspecting its Dockerfile which hopefully is linked from the registry. If there is no Dockerfile linked from the registry page, you may be out of luck. 
 
+Example image dependency 
++++++++++++++++++++++++++
 
-If the Dockerfiles of the images are linked in the registry we can trail though the dependencies of the base images used by the python image. What we find if we select the latest bookworm tag is the following: 
+Let's check the `Dockerhub python registry <https://hub.docker.com/_/python>`_. We can click on the link of the latest bookworm tag in the  and it leads us to its `Dockerfile on Github <https://github.com/docker-library/python/blob/7c8595e8e2b1c8bca0b6d9d146675b94c2a37ec7/3.13/bookworm/Dockerfile>`_ . Here we can see that Dockerfile is based on a base-image `buildpack-deps:bookworm`. We can do the same exercise for the image `buildpack-deps:bookworm` by finding the image in a registry like Dockerhub, navigating to the Dockerfile linked from that registry, and so on.
