[web-devel] Yesod, picture uploading, storing, rendering

In general, the recommended approach is to store binary files on the
filesystem instead of in the database. In the Yesod wiki, I violate
that :(. It's significantly more complicated than what you're looking
for, since it's parsing an entire ZIP file and pulling out
DITA-formatted XML, but you can look at the relevant file:

Note that I currently base64-encode the content since HDBC-postgresql
has problems with binary data. I'm hoping that gets resolved (or that
we move over to Chris's new PostgreSQL library).
