It looks like you’ve pinned the version of Images you’re using somehow.

Are any of them pinned in the manifest file C:\Users\gerso\.julia\environments\v1.1\Manifest.toml?

Some of them are fixed in the manifest file.

and how do I know if it is fixed or not?

Excuse my ignorance but I’m just starting to use Julia.

Hmm, looks like the docs omit the fact that you’d have to issue that from the relevant directory. Try cloning https://github.com/JuliaImages/juliaimages.github.io and then issue that command from the docs/ directory (which has the path you’re asking about).

There are many easy-to-access images in the TestImages package, where you can use testimage("lighthouse") from any directory.
