I read a couple of messages regarding displaying an entire 320x240 image on
the screen.  If you want an easy and crude way of doing it, you can use the
LoadImage to move the entire image into your display and swap buffers
instead of using 2 sprites, and just use a main loop that does nothing but
swap buffers.  Like this:

...
   GsGetTimInfo((u_long *)(PICTURE+1),&Image);
   Rect.x = 0;
   Rect.y = 0;
   Rect.w = 320;
   Rect.h = 240;
   LoadImage(&Rect,Image.pixel);
   Rect.y = 240;
   LoadImage(&Rect,Image.pixel);

   while(PadRead(1) != PadSelect)
   {
      Buffer = GsGetActiveBuff();
      GsSetWorkBase((PACKET *)Packet[Buffer]);
      GsClearOt(0,0,&OT[Buffer]);
      DrawSync(0);
      VSync(0);
      GsSwapDispBuff();
      GsDrawOt(&OT[Buffer]);
   }
...

This is not useable for background images in games and only works with
images that includes the CLUT information in the data, but it's a great way
to do a quick display of a title image for example.
