showimg is a function of the npc, so all players would see it. Also the timeout variable belongs to the npc, so it doesn't matter who the active player is, it would always set the timeout for the npc.

If you want to change something on the clientside you will need to set strings for the player (setstring client.name,value; or setstring clientr.name,value; ) and possibly do a trigger (like triggeraction 0,0,clientside, weaponname,params; ) and on clientside you then display an image or similar when the string is set or when the trigger is received (if (actionclientside)...)
