Just finding this old issue regarding downloading blobs. Nice work!

<img width=""212"" alt=""image"" src=""https://user-images.githubusercontent.com/4997607/104946741-df4bad80-59ba-11eb-96e3-727c85cc4dc6.png"">

As a feature request, maybe it would be possible to assign a blob column as a certain data type (e.g. `.jpg`) and then each blob could be downloaded as that type of file (perhaps if the file types were constrained to normal blobs that people store in sqlite databases, this could avoid the execution stuff mentioned above).

I guess the column blob-type definition could fit into this dropdown selection:

<img width=""201"" alt=""image"" src=""https://user-images.githubusercontent.com/4997607/104947000-479a8f00-59bb-11eb-87d9-1644e5940894.png"">

Let me know if I should open a new issue with a feature request. (This could slowly go in the direction of displaying image blob-types in the browser.)

Thanks for the great tool!

perhaps this is already possible in some form with the plugin datasette-media: https://github.com/simonw/datasette-media","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",725996507,

quick test of the downloaded blob:

```
>>> import imghdr
>>> imghdr.what('material_culture-1-image.blob')
'jpeg'
```

The output plugin would be cool. I'll look into making my first datasette plugin.  I'm also imagining displaying the image in the browser -- but that would be a step 2.
