How to map image field?

Yes, that makes sense. But is not in the scope of this module to provide that URL.

I think you should create a computed field that computes the absolute file/image URL. Then map that field.

Also note that there's ✨ Add a computed 'file_url' property to FileItem (for exposing file URL in file field normalization) Needs work aiming to fix this in core. With this you can map directly the computed property.

No feedback since. Is this still an issue. If not, please close.
