Clients cannot see custom textured flags on Host server

[RaptorElite 0]

So I'm using "this setFlagTexture "media\images\Estonia.jpg";" command in the init line of a white flag but the thing is whenever I host a server , my friends cannot see them ie. the flags are just blank, even though I have given the correct directory they cannot see it at all
Can anybody help?

if (isServer) then
{
	this setFlagTexture "media\images\Estonia.jpg";
};
