ImagesCollide

In regular blitz you'd get an error 'not enough parameters' if you didn't specify a frame with imagescollide.
This works in Bmax...

Graphics 640,480
image1:TImage=CreateImage(128,128)
image2:Timage=CreateImage(128,128)
SetColor 255,0,0
DrawRect 0,0,128,128
GrabImage(image1,0,0)
Cls
SetColor 0,0,255
DrawOval (0,0,128,128)
GrabImage(image2,0,0)
SetColor 255,255,255
While Not KeyHit(key_escape)
  Cls
  DrawImage image1,100,100
  DrawImage image2,MouseX(),MouseY()
  If ImagesCollide(image1,100,100,0,image2,MouseX(),MouseY(),0) DrawText "Collided",0,0
  Flip
Wend
End

Can you show some code?
