But in fact it probably means this (a generic TIM image loader function):

void ProperInitialiseTexture (long address, GsIMAGE* imageInfo)
{
	RECT rect;
	GsIMAGE temp;

	// If we've not specified an image info structure, we're not
	// going to re-use the information (probably a texture for a 3D model)
	// so we use a local to stand in for it.
	if(imageInfo==NULL)
		imageInfo=&temp;

		// +4 because we need to skip head of TIM file
	GsGetTimInfo( (u_long *)(address+4), imageInfo);

	dumpIMAGE(imageInfo);

	rect.x = imageInfo->px;	
	rect.y = imageInfo->py;		
	rect.w = imageInfo->pw;	
	rect.h = imageInfo->ph;	

	LoadImage(	&rect, imageInfo->pixel);
	DrawSync(0);

		// if image needs a CLUT, load it up 
		// (pmode: 8 or 9 ==> texture is 4-bit or 8-bit)
	if ( (imageInfo->pmode>>3)&0x01) 
	{
		rect.x = imageInfo->cx;	
		rect.y = imageInfo->cy;	
		rect.w = imageInfo->cw;	
		rect.h = imageInfo->ch;	

		LoadImage( &rect, imageInfo->clut);
		DrawSync(0);
	}

		// wait for loading to finish
}

Yeah, let's lose that one....

Also, where's your CLUT positioned?

Good idea. Start off with just an object with no texture, get it to display
then
try an object with textures.

Fame at last :)

RsdANIM save's TMD's you know....
