[support] How to know if a post is new or not for an user (authenticated)

Hi all. I need to create a page (I will use views) that contains all my 20 last posts. But I need to attach an image to the new posts. Obviously "new" mean "the post the the authenticad user has not see". Is there a modulo or a snippet or a howto or a RTFM ?
