images=db(db.image.blog_id==db.blogposts.id).select(db.image.ALL) Here you are saying to the database to do exactly what you don't want...
You should pass the id of your db.blogposts and not all the ids... Try : images=db(db.image.blog_id==1).select(db.image.ALL) If there is a blogposts that have id 1... You should have only the images associates to this blogposts record...
