This thread is resolved. Here is a description of the problem and solution.
Problem: How to completely remove the images that are in the secondary languages that do not exist in the default language?
Solution: At this time, this is not possible with the WPML and its addons.
Using SQL would be possible to try to find records which are in the secondary languages and does not exist in the default language. Then use another query to delete it based on the trid column (translation id). But this should be a complex query.
