I didn't get it to work, so I created a workaround: Two additional fields linked to the next or previous key name. These links are updated by for loop over the sequence. If I get more pictures or I have to be more dynamic with the sequence I have to add some more logic to keep the links updated with a single operation instead of a big loop. Grace to the initial concern it's a poor workaround.
