"normally": you are right. But this it is not first time I have noticed whe all pics of a movie are changed for DVD quality, their first providers are deleted. And this is not my case.

I have no problem to send a private message to Valiant but you must understand an user can't work as a "police" checking all his past submited pics and what can be happening about them. I waited that the situation I explain in my post (probably and partialy unintelligible for my bad english) must be shared among all moderators, and when they change pictures of a movie (all or part of them and I repeat, well done when they change pics for a better ones with DVD quality) preserve and respect the previuos users that are showed as providers of that movie so these first users were who submited the first pics of that movie and in "Comments" of that movie repeat again their previous pics(changed) as usual: "XXXX wrote + changed picture".

There isn't problem antp.
