place.birds	sighting	type: blob, thumbnail, alt text,
town.walls	photo	type: blob, accept: image/*, alt text, syndication (array for records referencing image), #aspectRatio

aspectRatio is typically defined like so:

    "aspectRatio": {
      "type": "object",
      "required": [
        "width",
        "height"
      ],
      "properties": {
        "width": {
          "type": "integer",
          "minimum": 1
        },
        "height": {
          "type": "integer",
          "minimum": 1
        }
      }
    }

To serve more use than just a record holding the blob, a community lexicon for images should include at least the blob type , accept all image/* options, and alt text. One interesting question from reviewing the above table: is this just for image blobs, or any image? That could change the structure. Below I'm focused on just image blobs.

Common or likely-widely-useful additional fields worth considering:
- #aspectRatio
- atproto #selfLabel

Interesting fields whose use may not be as universal:
- creator
- contributor(s)
- tags / keywords
