I want to get all Images not used by current ItemID. The this subquery but it also always returns duplicate Images:

EDITED

select  Images.ImageID, Images.ItemStatus, Images.UserName, Images.Url, 
        Image_Item.ItemID, Image_Item.ItemID
    from Images 
        left join (select ImageID, ItemID, MAX(DateCreated) x
                        from Image_Item 
                        where ItemID != '5a0077fe-cf86-434d-9f3b-7ff3030a1b6e'
                        group by ImageID, ItemID 
                        having count(*) = 1)
        image_item on Images.imageid = image_item.imageid 
        where ItemID is not null

I guess the problem is with the subquery which I can't avoid duplicate rows:

select ImageID, ItemID, MAX(DateCreated) x
    from Image_Item 
    where ItemID != '5a0077fe-cf86-434d-9f3b-7ff3030a1b6e'
    group by ImageID, ItemID 
    having count(*) = 1

Result:
