We don't have the capacity to search for your old posts and remove them. If you want to remove your old posts, you can edit them to remove your pictures.
In the future, saying "please delete that one post in that one thread" makes it hard to know what you are talking about. Please provide links as we don't have the time or desire to search for stuff like that.
