Permission to "delete," but not delete image, only hide from user

Description of the issue
I need an initial statement so I can implement the following function:

With delete permission enabled, but I want to change the delete function.

What would have to be done when deleting IMAGE:
> "DELETE" IMAGE
1) Instead of delete from in the table images, execute update in column USER_ID switching to VISITOR. Hiding from his vision.
2) Do not delete image from folder.

> "DELETE" ALBUM
What would have to be done when deleting ALBUM:
1) Instead of delete from in the table album, execute update in column USER_ID switching to VISITOR. Hiding from his vision.
2) Do not delete image from folder.
3) UPDATE images to album NULL.



Is there any other problem?

Where do I start? Do you already have something similar ready?

Incorrect translation! 🙁, so I was not finding.

msgid "Enable user content delete"
msgstr "Ativar códigos embed (conteúdo)"

msg correct:

"Permitir usuário deletar o próprio conteúdo"
