We cannot really take action for floating off a picture since it is very likely to be a ghost, a player who has a model floating in the air when they are in fact not there. Thank you for trying to help make our server a better place though and keep up the good work.
P.S. A good way to check and see if the player you see is a ghost is to check and see if the player is online. If he isn't then he is a ghost. If he is online then have him tell you where he is because they can sometimes be somewhere else on the map without even knowing he has a ghost.
