A picture of the remains of the flower after it has bloomed. I suppose these are the seeds. Notice that the structure of the flower has turned purple.
As mentioned in response to one of your previous posts, this is elderberry, Sambucus spp. The purple colored 'seeds' are on their way to becoming ripe elderberries.
Yes - it's an Elder. If you have multiple pictures it gets rather confusing quite quickly as they immediately start to drift apart on the page if they are all in separate posts. To add pictures to your post you can reply to your own post. If the site won't let you just alter the heading slightly.
