The forum's BBcode isn't quite intelligent enough to figure out certain things but it seems you've successfully linked to the images now anyway.
The only other thing I would mention is to perhaps reduce the image size when directly previewing the images in the post (i.e. using img tags rather than links) especially when including multiple images, as some people still have less-than-stellar download speeds. As it is the forum scales it down to a maximum of 835px wide anyway, but needs to first download the entire image in order to do so.
