Attacheck images on top

Hi, on our site, if we attach an image to a post, in the geed, the image will appear as the first element of the post. That is, it will appear before the block with the name and photo of the poster, the time etc.

In this forum I notice that the order is reversed, the block with the author name and image is always on top of the post.

Does anyone know how we can achieve that on our forum as well?

Thanks!
