UICollectionViews to select 2 Images, one on top of the other - ios6

Question

I have mainView with an image displayed (Using Storyboards and imageViews and CollectionViews) when I select an cell from my CollectionView (in a popOver).
How do I create another (popover containing a UiCollectionView) that let's me select an image and place that second image on top of the one I already have displayed?
