Problem with Render

[Overkillz]

Hey everone, Im trying to render a imagen using a server event"onPlayerLogin", but It doesn't work, Im too nab on Script, Im learning and I hope you can fix this error:

- Cliente

addEvent('Shimu', true) 
function Shimu ( ) 
    addEventHandler("onClientRender", getRootElement(), shimuLoading) 
end 

- Server

addEventHandler('onPlayerLogin', root, ------Will not be "root" 
   function ( ) 
    triggerClientEvent(source, 'Shimu', source ) 
    end 
  ) 
  

Thanks and regards.

    addEventHandler("onClientRender", getRootElement(), shimuLoading) 
end 
addEventHandler("Shimu", getRootElement(), Shimu)
