controlling background placement && turning off bkgrd tiling

Hi Everyone,
           Trying to get this clear in the mind. Is there a way to 
           control background images on a page so that you can layer 
           their placement or quadrant including default painting for 
	    browsers that do not load backgrounds. Also since this has 
           long since left the braincells is their a way to get a 
           background image not to tile but take image and turn off
           tiling of image used as background. I am sure there is but 
           can't seem to remember for the life of me:'(

							TIA
