I don't see what is wrong with this...you posted a picture of someone staring up at the night sky in Minecraft...
I believe your picture doesn't really show anything useful. However, if that is your problem, then you need to let his computer download and render enough of the map so that he can stand. This shouldn't cause him any damage when the map is loading and it should go away in a few seconds. If you don't want this to happen, get a better server.
