First, add a JS file in `metadata.yaml`:

```yaml
extra_js_urls:
  - '/static/app.js'
```
then inside the script, find the blob download links and replace `.blob` extension in the url with `.jpg` and replace the links with `<img/>` elements. 
You need to add an output formatter to serve `BLOB` columns as JPG. You can find the code in the first post.
~~Replacing `.blob` -> `.jpg` might not even be necessary, because browsers only care about the mime type, so you only need to serve the binary content with the right `content-type` header.~~. You need to replace the extension, otherwise the output renderer will not run.

```js
window.addEventListener('DOMContentLoaded', () => {
    function renderBlobImages() {
        document.querySelectorAll('a[href*="".blob""]').forEach(el => {
            const img = document.createElement('img');
            img.className = 'blob-image';
            img.loading = 'lazy';
            img.src = el.href.replace('.blob', '.jpg');
            el.parentElement.replaceChild(img, el);
        });
    }

    renderBlobImages();
});
```

while this does the job, I'd prefer handling this in Python where it belongs.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",860625833,

But to generate a URL, I need the primary keys, but I can't call `pks = await db.primary_keys(table)`  inside a sync function. I can't call `datasette.utils.detect_primary_keys` either, because the db connection is not publicly exposed (AFAICT).
