default photo for thumbnail?

[sheppard]

It would be nice to have a thumbnail to use in observation lists and map popups. One way to do this would be through a custom ObservationSerializer field that would scan the JSON data for photo references and return the first one.

Yes. For the map browser (more usable on larger screens) I'm not planning on using popups: just 2 or 3 fields for hover, and on click the whole parsed object will go into an expandable sidebar, and for this I would want more than the 160px thumbnails but perhaps the 1024 size.

I want to learn how to do serializers, and wonder for down the road if it might be possible to load data in response to a geographic query, e.g. features within a bounding box, and query differences over time between observations.
