I mean is there a Depth thing like example:

Image1=Depth(0)
Image2=Depth(-1)
Image 1 is over Image 2

Anything like that? or its the first image drawn is under second image?

The last image you draw is displayed at the front.
You just need to sort out the order in which you draw your images.

Okay got another question, if I want a background image to be tiled all over my map like "grass"
is there an easy way or do i need to do
the layer things with
1,1,1,1,1,1,1,... and so on?

Check the "TileBlock" and the "TileImage" commands

Something like this perhaps (for the Depth question), I don't have B+ but it works in Blitz3D:

Graphics 640,480,32,2
SetBuffer BackBuffer()
Const MAXDEPTH = 3

Type zImage
	Field Image
	Field Depth%
	Field X
	Field Y
End Type

imgCow.zImage = New zImage
	imgCow\Image = LoadImage("cow.bmp")
	imgCow\Depth = 0
	imgCow\X = 50
	imgCow\Y = 50

imgHorse.zImage = New zImage
	imgHorse\Image = LoadImage("horse.bmp")
	imgHorse\Depth = 1	
	imgHorse\X = 55
	imgHorse\Y = 55

imgDog.zImage = New zImage
	imgDog\Image = LoadImage("doggy.bmp")
	imgDog\Depth = 2
	imgDog\X = 60
	imgDog\Y = 60


;MAIN GAME LOOP
While Not KeyDown(1)

	DrawImageByDepth()
	Flip
	Cls
	
Wend

End
;END MAIN GAME LOOP


Function DrawImageByDepth()
;VARS
Local iDepthLoop

;MAIN FUNCTION CODE
For iDepthLoop = 0 To MAXDEPTH
	For tempImg.zImage = Each zImage
		If tempImg\Depth = iDepthLoop Then DrawImage tempImg\Image, tempImg\X,tempImg\Y
	Next
Next

End Function
