This probably happens when a user requests an image, leaves the app, comes back a few hours later (after the stable horde backend has expired the image).

To fix this, I think we can either:

• Have the app request the image in the background.
• Have our own simple backend that requests the image and persists it.

(I would prefer the second option since it would be more robust, but it's more work).

I think we should punt on this for the time being, since it's a big architectural change. Let's focus on the easier issues, and revisit this once other stuff is more stable.
