[HELP] Why not working the image in nametag?

[Tokio]

client:

					if getElementData(player, "showImage") then
						dxDrawImage (sx-34, sy-95, 55, 55, 'logo.png' )
					else
						dxDrawImage (sx-34, sy-95, 55, 55, 'air.png' )
					end

server:

function setDataOnLogin(player) 
	if isObjectInACLGroup("user."..getAccountName(getPlayerAccount(player)),aclGetGroup("FoAdmin")) then
        setElementData(source, "showImage", true) 
    end 
end 
addEventHandler("onPlayerLogin", root, setDataOnLogin) 
  
function setDataOnResourceStart(player) 
    for i, v in ipairs(getElementsByType("player")) do 
	if isObjectInACLGroup("user."..getAccountName(getPlayerAccount(player)),aclGetGroup("FoAdmin")) then
            setElementData(v, "showImage", true) 
        end 
    end 
end 
addEventHandler("onResourceStart", resourceRoot, setDataOnResourceStart) 
  
function removeDataOnLogout() 
        setElementData(source, "showImage", false) 
end 
addEventHandler("onPlayerLogout", root, removeDataOnLogout)

Your player parameter is undefined, get the player from the value when looping

function setDataOnResourceStart() 
    for i, v in ipairs(getElementsByType("player")) do 
		if isObjectInACLGroup("user."..getAccountName(getPlayerAccount(v)),aclGetGroup("FoAdmin")) then
            setElementData(v, "showImage", true) 
        end 
    end 
end

addEventHandler("onResourceStart", resourceRoot, setDataOnResourceStart)
