+- Credit photographers — these photos are all some variation of CC-BY so we need to give attribution
+- Add filtering by region — the metadata already exists, though perhaps needs to be adjusted
+- Refactor — perhaps needs to be more object oriented
+- Make a web frontend — I can imagine a light frontend that would shuffle the images in realtime and allow generation of a number of cards
