Sky changing and rotating

[Milandrag]

i can get my pictures to see them, but when i send map to my brother he doesn't see them, although he has them at same location as i do. even when i restart the map, i again see the default sky instead of my custom sky. i have also tried to save map after i've loaded sky but its all the same. so what else should i do beside /loadsky "blah/blah/blah" to keep my sky attached to map?
