Intel File doesn't show up in multiplayer

 GOM_fnc_shownImage1 = true;

   intelIMG1 = findDisplay 46 ctrlCreate ["RscPicture", -1]; 
   intelIMG1 ctrlSetPosition [ 0.5 - ( 350 * pixelW ), 0.5 - ( 350 * pixelH ), 700 * pixelW, 700 * pixelH ];

I have this code inside an intel file, that is supposed to show a picture (Located inside the mission folder), but it doesn't work for other people, only for myself when in multiplayer.

What is happening?
