title: Multiple selectable GridView
body: <p>OK, so I think I've exhausted searching for this question, and it's either that I'm totally missing something or nobody else has tried to create a GridView (showing images) which allows the user to select multiple images.  Basically I want to have the orange selection box appear whenever a user selects an image, or disappear if the user has already chosen the image.</p>
  
  <p>Is this something that I'll have to roll myself with a customer View?  I may also try including a CheckBox with each image and have the CheckBox selected if the image is.</p>
  
  <p>Any assistance would be greatly appreciated.</p>
