Argo CD Image Updater Comportement in edge cases

[sbrunner]

What's the comportment of Argo CD Image Updater if we defined an image in the image-list but we didn't define the helm.image-name and the helm.image-tag?
And the opposite (define the helm.image-name and the helm.image-tag but the alias is not present in the image-list)?

The problem I am trying to solve is that our Applications are generated from an ApplicationSet then all the Applications have the same annotation, and I plan to try to use the {{path.basename}} to differentiate the applications.
Note that the Application can have a different version of the same app in a preview to do a blue/green switch.

After some try I saw that:

If we defined an image in the image-list but we didn't define the helm.image-name and the helm.image-tag ArgoCD Image Updater will use image.name and respectively image.tag.

And if we have the helm.image-name and the helm.image-tag but the alias is not present in the image-list ArgoCD Image Updater will just ignore them.
