title: positioning images within Group
body: <p>How do I position individual images within a image group?</p>
  
  <p>I'm currently using the following code:</p>
  
  <pre><code>--category 1
  local light1 = display.newImage("Images/Category 1/pistol1.png")
  local light2 = display.newImage("Images/Category 1/machinePistol1.png")
  
  --category 1 image group
  local lightGroup = display.newGroup()
  lightGroup.x, lightGroup.y = 100, 150
  lightGroup:insert( light1 )
  lightGroup:insert( light2 )
  lightGroup.isVisible = false
  </code></pre>
  
  <p>But it places both the images on top of each other.</p>
