Observed behavior:
When swapping back and forth between photos in the Gallery app using the arrow keys keyboard shortcut, photos shift horizontally before loading, and show pixelated while loading. This occurs even on photos that are all locally stored. The overall experience paging through multiple photos is jarring.

Expected behavior:
We should cache the images and make swapping back and forth between multiple photos much faster, with no shifting of the image before displaying in its final location.
