probably , first step to check..if you want to add new map marker then make sure image file is correct and its extension also.. by default it may be .bmp or .png (dont remember exactly from head) ..

Under Before first drawing, it won't let me add more markers. It seems to be limited to 5 svcMiniMapCommands. The images are showing up fine. I'm working on a spaceship project, so the map is pretty open, so I use a grid image for the map image. I just want to show ships and navigational buoys. It works, I just can't add anything beyond 5 items. Am I doing something wrong? I hope I'm making sense.
