You can do it with prePersistPostEntity() method in your controller. You need to define it and iterate over image collection creating Image entities and persisting them to database.

Also, if you need to edit the Post and manipulate its images collection you need to consider defining preUpdatePostEntity() method that would check for missing images and create them like in "persist" event.

Closing as fixed by @forsetius comments. Thanks!
