Try this code: I didn't check if it works, but it should! Replace FILENAME.BMP with the filename of you image file.

[edit] Hupps, bei dir kann ich ja deutsch schreiben
Versuch diesen Code mal. Ich weis nicht ob er funktioniert, da ich auf arbeit sitze und ihn ausm Kopp geschrieben hab

Code:

---

bmap sr_games = "FILENAME.BMP";

Panel intro1
{
	bmap = sr_games;	
}

function main()
{
	tex_share = on;

	splashscreen.pos_x = (screen_size.x - bmap_width(splashmap))/2;
	splashscreen.pos_y = (screen_size.y - bmap_height(splashmap))/2;
	intro1.pos_x = (screen_size.x - bmap_width(sr_games))/2;
	intro1.pos_y = (screen_size.y - bmap_height(sr_games))/2;
	
	splashscreen.visible = on;
	wait(3);	

	level_load(level_str);
	freeze_mode = 1;


	sleep(1);
	splashscreen.visible = off;
	intro1.visible = on;
	wait(-1);
	intro1.visible = off;
	bmap_purge(splashmap);

	load_status();

	msg_show(mission_str,10);

	ifdef CAPS_FLARE;
	lensflare_start();
	endif;

	move_view_cap = 1;

	freeze_mode = 0;
}
