It's in this bit of code:

	imagebank=LockedPixels(buffer) 
	pitch=LockedPitch(buffer) 
	
	; copy bank to image line by line 
	For y=0 To DHEIGHT-1 
		yoff=y*pitch 
		For x=0 To DWIDTH-1 
			PokeInt imagebank,yoff+(x*4),image(x,y) 
		Next 
	Next


For the "Y increment" you need to use the pitch (LockedPitch(buffer)) of the screen buffer instead of Graphicswidth()*4 as these two values can vary. This is the problem I ran into when first experimenting with LockedPixels.
