I can write a custom Datasette plugin which takes the `uuid` from the URL, looks up the path, then serves up a thumbnail of the jpeg or heic image file.

I'll prototype this is a one-off plugin first, then package it on PyPI for other people to install.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",613006393,

First, install `datasette` and the `datasette-media` plugin.

Create a `metadata.yaml` file with the following content:

```yaml
plugins:
  datasette-media:
    photo:
      sql: |-
        select path as filepath, 200 as resize_height from apple_photos where uuid = :key
    photo-big:
      sql: |-
        select path as filepath, 1024 as resize_height from apple_photos where uuid = :key
```
Now run `datasette -m metadata.yaml photos.db` - thumbnails will be served at http://127.0.0.1:8001/-/media/photo/F4469918-13F3-43D8-9EC1-734C0E6B60AD and larger sizes of the image at http://127.0.0.1:8001/-/media/photo-big/A8B02C7D-365E-448B-9510-69F80C26304D

I also made myself two custom pages, one showing recent images and one showing random images.

To do this, install the `datasette-template-sql` plugin and then create a `templates/pages` directory and add these files:

`recent-photos.html`
```html
<h1>Recent photos</h1>

<div>
{% for photo in sql(""select * from apple_photos order by date desc limit 100"") %}
    <img src=""/-/media/photo/{{ photo['uuid'] }}"">
{% endfor %}
</div>
```

`random-photos.html`
```html
<h1>Random photos</h1>

<div>
{% for photo in sql(""with foo as (select * from apple_photos order by date desc limit 5000) select * from foo order by random() limit 100"") %}
    <img src=""/-/media/photo/{{ photo['uuid'] }}"">
{% endfor %}
</div>
```

Now run `datasette -m metadata.yaml photos.db --template-dir=templates/`

Visit http://127.0.0.1:8001/random-photos to see some random photos or http://127.0.0.1:8002/recent-photos for recent photos.
