imageOverlays property

A collection of overlays for displaying images in the view.

An image overlay collection cannot belong to more that one GeoViewController.

If the collection contains multiple image overlays, they display in the order in which they were added to the collection.

So the first overlay in the collection (at index 0) displays at the bottom and each one that follows displays on top of the previous ones.

If the GeoViewController also has a GraphicsOverlay, it displays on top of the ImageOverlay.
