Fiddle Choose Photo UI

Here's the choose photo menu in Fiddle.

The user triggers this menu by edge swiping from the bottom of the screen, thus the slightly different treatment for the drag-to-close button.

Also, the background of this menu is the image they're currently editing with a blur applied. Should make the animation of the menu opening/closing a bit more interesting.

They can also browse groups of photos by tapping on a pile and triggering a springboard folder type of animation (view attachment for that treatment).
