This is because not all tim files have clut information. check the pmode
field to see if it is present.

Also note that you should do a DrawSync(0); after a LoadImage or just
before you use the memory used by it to ensure that it's operation has
completed.  Its non-blocking.

Yep its fine, this tim has clut information.

Your picture doesn't have clut information.  And you program does not
try to load it.  The program is fine, as is the picture.

I hope this is of some help.
I have attached a bit of code from the chrome demo that loads the
textures.

void InitialiseTexture(u_long *timAddr)
	{
	GsIMAGE image;
	RECT t,c;

	GsGetTimInfo(++timAddr,&image);

	setRECT(&t,image.px,image.py,image.pw,image.ph);
	LoadImage(&t,image.pixel);
	DrawSync(0);
		
	// load CLUT as necessary
	if (image.pmode & 8)
		{
		setRECT(&c,image.cx,image.cy,image.cw,image.ch);
		LoadImage(&c,image.clut);
		DrawSync(0);
		}
	}
}
