title: iphone - Can you add an image created by the phone to a MKOverlay?
body: <p>I've been following the WWDC Sesion 127- Customizing Maps With Overlays. They say you can get the image to use as a MKOverlay either from the apps bundle or from the network. I would like to know if the image can be generated by the phone using it's APIs.</p>
  
  <p>Has anyone done it? Can you maybe provide a tutorial?</p>
  
  <p>Thanks.</p>
  
  <p>[EDIT]
  I would also actually need a tutorial on how to add that image, created by the phone or downloadded from the network, to the map.
  All I see is the WWDC demo but you need the ticket to the conference, wich I obviously dont have.</p>
