Hi everyone,

I have looked at how to insert photos in mission and followd directions but photos keep coming up totally black. Any ideas why? how to fix?

I have pic in mission folder and the following in breifing.sqf :

Switch (side player) do
{
   
   case WEST: // BLUFOR briefing goes here
   {
      player createDiaryRecord["Diary", ["Info", "<br/>Captain Bravo<br/>Version 1.03<br/>"]];
      player createDiaryRecord["Diary", ["Enemy forces", "<br/>Enemy forces are expected to be around 200 troops. Mostly lightly armed. <marker name='mebase'>base</marker> as us,<img image='rebel_leader.jpg' width='150' height='150'/> so stay alert!"]];

Any tips are always appreciated.
